Multiply (2x+5) times (x2+6x-10) ? Thank you:)

Answer:

  62.9 square units

Step-by-step explanation:

The area of a composite shape is the sum of the areas of the parts. Here the shape consists of a positive rectangle that has dimensions 8 × 11, together with a negative half circle of radius 8/2 = 4. That is, the area of the half-circle is subtracted from the area of the rectangle, as the problem statement tells you.

__

The area of a rectangle is the product of its dimensions:

  A = LW = (11)(8) = 88 . . . . square units

The area of a semicircle is half the area of a circle, so will be given by the formula ...

  A = 1/2πr^2 = 1/2π(4^2) = 8π ≈ 25.1 . . . . square units

The area of the figure shown is the difference between the rectangle area and the semicircle area:

  total area = rectangle area - semicircle area

  total area = 88 -25.1 = 62.9 . . . . square units

In the given diagram, The shown angles form Linear pair. And according to that property the sum of measures of the two Angles equals to 180°

Now, let's use the equation to solve for x ~

[tex]\qquad \sf  \dashrightarrow \:( 13x + 6) + (29x + 6) = 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 13x + 6 + 29x + 6= 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 13x + 29x + 6 + 6= 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 42x + 12= 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 42x = 180 \degree - 12 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 42x = 168 \degree [/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 168 \degree \div 42[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 4 \degree[/tex]

Answer:

[tex]\sf c = -4[/tex]  and  [tex]\sf b = -6[/tex]

Explanation:

using the formula: [tex]\sf x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Here the a = 1

using the equation:

[tex]3 \pm\sqrt{13}= \frac{ -b \pm \sqrt{b^2 - 4(1)c}}{2(1)}[/tex]

[tex]6 \pm2\sqrt{13}= -b \pm \sqrt{b^2 - 4(1)c}}[/tex]

matching the coefficients: b = - 6

find c:

[tex]6 \pm2\sqrt{13}= -(-6) \pm \sqrt{(-6)^2 - 4(1)c}}[/tex]

[tex]6 \pm2\sqrt{13}= 6 \pm \sqrt{36 - 4c}}[/tex]

[tex]\sf 6 \pm\sqrt{52}= 6 \pm \sqrt{36 - 4c}}[/tex]

[tex]\sf 36-4c = 52[/tex]

Answer:

3/6

Step-by-step explanation:

I think it is asking for an answer choice equal to 1/2, and 3/6 is equal to 1/2.

Do you have a picture of the actual question?

say the regular price is "x", which is the 100% of the value, and we know it's discounted by 40%, so that means 100% - 40% = 60%, and we know as well that that value is 1200, so.

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 1200&60 \end{array}\implies \cfrac{x}{1200}=\cfrac{100}{60}\implies \cfrac{x}{1200}=\cfrac{5}{3} \\\\\\ 3x=6000\implies x=\cfrac{6000}{3}\implies x=2000[/tex]

Part A

For this part, I'm assuming your teacher implies that we ignore the door, windows and rectangular opening. It seems like parts B and C cover this aspect.

There are 2 walls that are 20 feet by 10 feet. Each is 20*10 = 200 sq ft, so both opposite walls are 2*200 = 400 sq ft.

Then there are 2 more walls that are 15 ft by 10 ft. Each has area 15*10 = 150 sq ft, and doubles to 2*150 = 300 sq ft.

The total wall area (ignoring any openings/doors/windows/etc) is 400+300 = 700 sq ft.

Another way to get this answer is to find the perimeter of the floor rectangle to get 2(L+W) = 2(20+15) = 2(35) = 70. Then multiply this with the height of the room to get 70*10 = 700

Note: This ignores the windows/doors/any other opening

====================================================

Part B

Useful info to focus on:

There's no mention of a door (either front door or interior door to another room). Instead, your teacher talks about a rectangular opening which I'm assuming is the walkway to perhaps the kitchen and/or hallway or something. Though this rectangular opening might be part of or entirely the front door. It's not clear what your teacher means here. I'll just forget about the door part.

Fact1 and fact2 tell us we have 3+2 = 5 windows of 3 ft by 8 ft. Each window has area 3*8 = 24 sq ft. Five of them give 5*24 = 120 sq ft

Fact 3 says we have a rectangular opening of area 7*8 = 56 sq ft.

The total area of all items mentioned is 120+56 = 176 sq ft

====================================================

Part C

We subtract the results of the previous parts A and B

wall area to paint = A - B = 700 - 176 = 524 sq ft

We're told that "The cans of paint Kamrie will purchase cover 415 square feet." So we'll divide the total area over the area per can.

524/415 = 1.26265 which is approximate

Round up to the nearest whole number. We don't round down to 1 can because we'll come up short. Instead we round to 2 paint cans. Having extra leftover paint is handy in case Kamrie made a mistake somewhere.

For this entire problem, I'm ignoring the ceiling and focusing on the walls only.

Answer:

65 + 12.5v = m (M being free movie)

Step-by-step explanation:

65 for the original 65 poitns he gets for signing up, then if he gets 12.5 points for every movie he visits then you need to multiply 12.5 times the amount of movies he went to (v) so it would be 65 + 12.5v
v would need to be 11.6

If you do 210 - 65 thats 145, then you do 145 divided by 12.5 which would get you 11.6

Answer:

16 seconds

Step-by-step explanation:

So, we know that distance equals 100.

We also know that Dita covers 6.25 meters of this distance every second.

Since this is 6.25 PER second, we can write this as 6.25s, where s is seconds.

To find the seconds it takes to cover 100 meters in distance, we can write the following equation:

6.25s = 100

This makes sense, since the 100 meters in distance is equal to the rate of change in meters, times the seconds.

Now we just need to solve for s.

To do this, we must get s alone. We can do this by dividing 6.5 from both sides:

[tex]\frac{6.25}{6.25}s = \frac{100}{6.25}[/tex]  

     =

  s = 16

So this means the seconds it takes to go 100 meters is 16 seconds, your first answer option

Answer:

12 larave

Step-by-step explanation:

41 - 29

If Leroy's total count is 41 larvae. The number of larvae n Leroy counted last week will be 12.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Leroy didn't count many larvae. This week, he counts 29 larvae on the milkweed. For both weeks, Leroy's total count is 41 larvae.

We have to apply the subtraction operation, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

Total count = count for this week + count for last week

41 = 29 + count for last week

count for last week = 41 - 29

count for last week = 12

Thus, If Leroy's total count is 41 larvae. The number of larvae n Leroy counted last week will be 12.

Answer:

35

Step-by-step explanation:

Here is the full steps:

Distribute

-7(x+10)=7(5-x)

-7x-70=7(5-x)

Distribute

-7x-70 = 35-7x            → Answer for the attachment "35"

Add 70  to both sides of the equation

-7x-70+70=-7x+35+70

Simplify

-7x=-7x+105

Add 7x  to both sides of the equation

-7x+7x=-7x+105+7x

0 = 105

Hello! In this question, we will be plugging in values to fit the simplification process of the expression.
__________________________________________________________

Explanation:

We were given the expression: -7(x + 10) = 7(5 - x)

In order to simplify the expression, we would use the distributive property.

Solve:

-7(x + 10) = 7(5 - x)

Distribute the "7" to the terms inside the parenthesis (x + 10).

-7x + (-70) = 7(5 - x)

Distribute the other "7" to the terms inside the parenthesis (5 - x).

7x + (-70) = 35 - 7x

Since we are only looking for the values in the simplification process, the answer for the first box would be -70 and the second box would be 35.

Step-by-step explanation:

Hello!

Let's first convert 250 seconds to minutes.

Since 1 minute is 60 seconds:

The runner ran 1500 meters in 4 and 1/6 of a minute

Now we need to find the unit rate using this equation:    [tex]\frac{\text{x}}{\text{1 minute}} = \frac{1500}{4\frac{1}{6}}[/tex]

Cross multiply:

360 meters

Answer:

[tex]\displaystyle 360\:m./min.[/tex]

Step-by-step explanation:

When converting from a smaller unit to a bigger unit, use division, especially because you are converting from [tex]\displaystyle m/s[/tex]to [tex]\displaystyle m./min..[/tex]First, you divide 250 by 60 to get 4⅙ minutes. You will then divide 1500 by 4⅙ to get this:

[tex]\displaystyle 1500\:metres\:in\:4\frac{1}{6}\:minutes \\ \\ 360 = \frac{1500}{4\frac{1}{6}} \\ \\ \\ \boxed{360\:m./min.}[/tex]
