Answer:

x=-12

Step-by-step explanation:

first collect all the like terms -28x + 24 = 120-20x

then move variables and constants to the correct side -28x + 20x = 120-24

collect like terms again -8x = 96

divide both side by -8 so -8x/-x n 96/-8 you get x=-12 bc -8 time -12 = 96

Answer:

x = -12

Step-by-step explanation:

First, combine like terms

[tex]-4x-24x+24 = 10(12-2x)\\-28x+24 = 10(12-2x)[/tex]

Then, use the distributive property on the right side

[tex]-28x + 24 = 120 - 20x[/tex]

Now, add 28x to both sides to get the Xs all together

[tex]24 = 120 + 8x[/tex]

Next, subtract 120 from both sides:

[tex]-96 = 8x[/tex]

divide both sides by 8:

[tex]-12 = x[/tex]

This means the answer is x = -12

Answer:

Total Area = 1070 m^2

Step-by-step explanation:

we have 4 different surfaces

1. the ramp

[tex]A_r = 15\times 30\\\\A_r = 450[/tex]

2. the triangles

since they are the same we just multiply by two

[tex]A_t = \frac{8\times 10}{2}\\\\A_t = \frac{80}{2}\\\\A_t = 40[/tex]

so the areas of the two triangles is

[tex]2A_t = 2(40)\\\\2A_t = 80[/tex]

3. the bottom rectangle

[tex]A_{bot} = 10\times 30\\\\A_{bot} = 300[/tex]

4. the back rectangle

[tex]A_{back} = 8\times 30\\\\A_{back} = 240[/tex]

now add them together

[tex]A_T=A_r+2A_t+A_{bot}+A_{back}\\\\A_T = 450+80+300+240\\\\A_T = 1070\: m^2[/tex]

Step-by-step explanation:

4x³ = 36x

4x³ - 36x = 0

4x(x² - 9) = 0

4x(x + 3)(x - 3) = 0

Hence x = 0, x = -3 or x = 3.

Step-by-step explanation:

we have to wrote down all the possible 3digit numbers and calculatevtheir sum

259+295+529+592+925+

952=3552

(the digits cant be repeated because they are written on cards only once)

The sum of all possible scores  3552.

Probability is the measure of the likelihood that an event will occur in a Random Experiment. Probability is quantified as a number between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.

Given:

Joe is shown 3 cards marked 2, 5 and 9.

we have write all the possible 3digit numbers

First taking 2 at hundred place value

259

295

Now, taking 5 at hundred place value

529

592

Now, taking 9 at hundred place value

925

952

Now, add the above 3 digit numbers

=259+295+529+592+925+952

= 3552

Hence, the sum of all possible scores  3552.

Hence, the measure of the largest angle is degrees is [tex]5[/tex] degree, [tex]10[/tex] degree and [tex]15[/tex] degree and the largest angle is  [tex]15[/tex] degree.

What are the angles?

Angles are formed by two rays (or lines) that begin at the same point or share the same endpoint. The point at which the two rays meet (intersect) is called the vertex.

Here given that,

The sum of the measures of three adjacent angles is [tex]150[/tex] degree. The measures of the angles are in the ratio of [tex]1:2:3.[/tex]

Let one angle is [tex]x[/tex], second is [tex]2x[/tex] and the thirs one is [tex]3x[/tex].

As given that the sum of three angles is [tex]150[/tex] degree but we know that the sum of three angles is [tex]180[/tex] degree then,

[tex]x+2x+3x=180-150\\\\x+2x+3x=30\\\\6x=30\\\\x=\frac{30}{6}\\\\x=5[/tex]

Answer:

Step-by-step explanation:

We are to multiply the expression (7y^3/5)(6x+5/21y)

(7y^3/5)(6x+5/21y) = 7 * y * y * y/5 * 6x+5/21y

(7y^3/5)(6x+5/21y)  = y²/5 * 6x+5/3

(7y^3/5)(6x+5/21y) = y²(6x+5)/5*3

(7y^3/5)(6x+5/21y) = y²(6x+5)/15

Hence the product is y²(6x+5)/15

24 cubic inches

Step-by-step explanation:

Whenever you are finding the volume you have to multiply by two plus a number times two. For example, since there is two depths, you have to multiply 3 by 2 plus the next number. Then, since there is two sides, you multiply 5 by 2 plus the next number. Finally, since there is only one base, you don't have to multiply by two.

Given :

One root of a third degree polynomial function f(x) is –5 + 2i.

To Find :

The number and nature of all roots for this function.

Solution :

We know, there are exactly three roots in any third degree polynomial.

Also, we know complex roots always comes in pair i.e. the other root is the conjugate of each other .

So, other root is , -5 - 2i .

Also, since complex roots come in conjugate pair. So, third root cannot be complex.

Therefore, 2 roots are complex and 1 is real.

Answer:

f(x) has two imaginary roots and one real root.

Formula for area of hexagon is ((3*square-root 3)/2)*a^2.

Step-by-step explanation:

Given

y = 2x + 1 .....i)

y = 3x +2 .....ii)

Putting equation II in equation i

3x + 2 = 2x + 1

3x - 2x = 1 - 2

x = -1

Now putting x = -1 in equation i

y = 2* (-1) + 1

= -2 + 1

= - 1

Therefore x = -1 and y = -1

Answer:

Please check the attached diagram.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Analysis of y = - 3x + 2

Given the linear function

y = - 3x + 2

comparing with the slope-intercept form y = mx+b

The slope m = -3

The negative slope indicates that as the line on the line graph moves from left to right, the line falls.

In other words, the negative slope indicates that when x increases, y decrease, and vise versa.

Please check the attached graph of the function y = - 3x + 2. It is clear that when x increases, y decreases, hence the line falls when the graph of the line moves from left to right.

The red line graph represents the linear function y = - 3x + 2.

Analysis of y = 4x + 2   (When -3 is replaced by 4)

Now, when we replace -3 by 4 in the equation y = - 3x + 2, the equation becomes

y = 4x + 2

comparing with the slope-intercept form y = mx+b

The slope m = 4

The positive slope indicates that as the line on the line graph moves from left to right, the line rises.

In other words, the positive slope indicates that when x increases, y also increases, and vise versa.

Please check the attached graph of the function y = 4x + 2. It is clear that when x increases, y increases, hence the line rises when the graph of the line moves from left to right.

The blue line graph represents the linear function y = 4x + 2.

Analysis of y = 2   (When -3 is replaced by 0)

Given the equation

y = - 3x + 2

If we replace -3 by 0, the equation becomes

y = 0x + 2

y = 2

In other words, y = 2 represents a horizontal line because the horizontal line is of the form

y = k

where k is the y-intercept

here k = 2 is the y-intercept of the line y = 2.

Thus, slope zero means the value of y does not change no matter what we take or change the x-value.

The graph of line y = 2 is also attached which represents a horizontal line with slope 0 and y-intercept 2.

The green line graph represents the linear function y = 2.

Please check the graphs of all the lines.
