Question

The area of a rectangular pool is (14x^2+21x) square feet. If it is 7x feet long, what is the width, in feet?

Answer 1

you get (2x+3), because 14 divided by 7 = 2 and 21 divided by 7 = 3

Explanation:

Answer 2

(14x^2+21x) = 7x(2x + 3)

A= L * W

but L = 7x so W = 2x + 3

answer: width is (2x +3) feet
