The length of a rectangle is represented by the function l(x) = 5x. the width of that same rectangle is represented by the function w(x) = 2x^2 − 4x + 13. which of the following shows the area of the rectangle in terms of x?

Remember that the area of a rectangle is the length of the rectangle multiplied by the width of the rectangle.

In this case, we could say (where is the area of the rectangle):

Substituting the values the problem gave us for and , we can find the formula for in terms of , which is:

The formula for the area of the rectangle would be A(x) = 10x³ - 20x² + 65x.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
