Question

The rectangle below has an area of x^2- 25 square meters and a length of x+ 5 meters.
What expression represents the width of the rectangle?

Answer 1

Answer:

x - 5

Step-by-step explanation:

Area =  Length x Width

Area =  x^2 -25

If the length = x + 5

Area can be defined as (x + 5)(x - 5) as x^2 -25 is a difference between two squares

Therefore Width = (x + 5)(x - 5) / (x+5) = x - 5
