Question

If a area of a rectangle is 45... set up an equation that must be true: w = x L = x-4

Answer 1

Answer: x times (x-4)=45

Step-by-step explanation:

First since the area is 45 that’s what the equation has to be equal to.
To find the area you always have to do length times width. So the width (x) times the length (x-4) equals 45.
