Answer:

6x^2 + 6x + 6x + 6

Step-by-step explanation:

You're cross multiplying the numbers on the left with the numbers on the right. Here is the order you multiply them in to eliminate the brackets, aka simplify the equation.

Step 1: (this ....) x ( this ....)

Step 2: (this ....) x (.... this)

Step 3: (.... this) x (this ....)

Step 4: (.... this) x (.... this)

REMEMBER!! When you multiply numbers with x's in them, make sure that you're multiplying the X's together too. For example, 2x times 3x is 6x^2 NOT 6x. Why? x times x is x^2 (aka x squared)

Answer:

It should be 2

Step-by-step explanation:

If you where to round to the nearest 10nth

To round 18 to the nearest 10, we look at the 8 and see if it's greater than, less to or equal to 5.

In the number, 18, 8 is greater than 5.

8 > 5

So we round up.

Therefore, your answer is 20.

Answer:

512

Step-by-step explanation:

So the expression here is simply 8³.

And you have to write is out like this:

8×8×8

Solve the equation from left to right:

8×8=64

Continue:

64×8=512

Therefore, 8³ equals 512.

Answer:

n=60

Step-by-step explanation:

subtract 75 from 135

Final Answer: [tex]n =60[/tex]

Steps/Reasons/Explanation:

Question: Solve the equation [tex]n + 75 = 135[/tex].

Step 1: Subtract [tex]75[/tex] from both sides.

[tex]n = 135 - 75[/tex]

Step 2: Simplify [tex]135 - 75[/tex] to [tex]60[/tex].

[tex]n = 60[/tex]

Answer:

1 : 45

Step-by-step explanation:

225 divided by 5 equals 45. You can now use this ratio to determine the number of people with different amounts of buses; when you change x from 1 to n, you would need to multiply 45 by n, and you will have your new ratio column in the table.

Hope this helps :)

The equation which models the relationship expressed in slope intercept form ls y = 45x

Expressing the equation in the form :

Slope, b = (900 - 225) / (20 - 5) = 45

Using any (x, y) points on the table given to find the value of c :

225 = 45(5) + c

225 = 225 + c

c = 0

Hence, the equation which models the relationship is y = 45x

Step-by-step explanation:

I used trig functions to solve for them

1st I found the central angle and divided it by 10 to create myself a right triangle in the middle with an altitude.

I then found the 3rd angle using the triangle angle sum theorem and then used trigometic functions to solve for X

[tex] \begin{cases}h = - \frac{b}{2a} \\ k = \frac{4ac - {b}^{2} }{2a} \end{cases}[/tex]

The vertex of Parabola is the maximum/minimum point depending on the value of a.

h-value

[tex]h = - \frac{5}{2(1)} \\ h = - \frac{5}{2} [/tex]

k-value

[tex]k = \frac{4(1)( - 6) - {(5)}^{2} }{4(1)} \\ k = \frac{ - 24 - 25}{4} \\ k = \frac{ - 49}{4} \\ k = - \frac{49}{4} [/tex]

The minimum value is the value of k. Therefore the minimum value is - 49/4 at x = -5/2.

This is Calculus method. We simply differentiate the function then substitute y' = 0.

[tex]f'(x) = 2 {x}^{2 - 1} + {5x}^{1 - 1} - 0 \\ f'(x) = 2x + 5[/tex]

Substitute f'(x) = 0

[tex]0 = 2x + 5 \\ - 5 = 2x \\ - \frac{5}{2} = x[/tex]

Substitute x = -5/2 in the original equation.

[tex]f(x) = {( - \frac{5}{2} )}^{2} + 5( - \frac{5}{2} ) - 6 \\ f(x) = \frac{25}{4} - \frac{25}{2} - 6 \\ f(x) = \frac{25}{4} - \frac{50}{4} - \frac{24}{4} \\ f(x) = \frac{25}{4} - \frac{74}{4} \\ f(x) = - \frac{49}{4} [/tex]

Answer:

A

Step-by-step explanation:

From the information given:

To create the required stochastic matrix, we need to take parents who are shown to be vegetarian or nonvegetarian in the column and the children who are vegetarian or nonvegetarian into the row section.

So;

Vegetarian V → 70% →            nonvegetarian NV → 30%

nonvegetarian NV → 40%             vegetarian    V →  60%

                                                           V     NV

The 2x2 stochastic matrix  =     [tex]\left \Big { {{V} \atop {NV}} \right.} \left [\begin{array} {cc}0.7&0.4\\0.3&0.6\\\end{array}\right][/tex]

Answer: 5x + 16

Step-by-step explanation:

Hi! Your answer to this problem would be 624.

Step by Step Explanation: Subtract 422 with 76, add 135, subtract 45, add 110, and lastly add 58.

Subtract 422 with 76, 422-76=366.

Add 366 with 135, answer will be 501.

Subtract 501 with 45 since she paid $45. 501-45=456.

Add 456 with 110 and that would be 566.

For the last step add 58 to find the answer and you would get 624.

Final Result: 624.

Answer: $350.00

Step-by-step explanation:

Answer:

$350

Step-by-step explanation:

if the sale is 30% we have to find what is 30% of 500 so we can subtracted from what we pay .

line up what you know:

$500 represents  100%

    $x represents  30 %

cross multiply

x*100 = 500* 30 ; divide both sides by 100

x= 500*30 /100 = 150

the sale price is 500-150= $350
