Question

If a storm window has an area of 640 square inches, what is the equation to find the dimensions when the window is 20 inches higher than it is wide (x represents height)

Answer 1

okay, so if height is x, what can you say about the width?

Answer 2

x+20

Answer 3

x-20

Answer 4

right. x is height, x - 20 is width. so what is the area of a rectangle whose height is x and whose width is x -20?

Answer 5

x(x-20)=640
