x-4

Step-by-step explanation:

The area of a rectangle can be expressed as the width multiplied by the length. Therefore, you can work backwards to find the length by dividing the area by the width. x^2-16 factors out to be (x-4)(x+4), which when divided by (x+4) yields the length of the rectangle to be (x-4). Hope this helps!

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. : )
