The area of a rectangular pool is given by the expression: A=12x+36

Factor the expression to determine the length and width of the pool. If the length of the pool is 12 and x=20, what is the width of the pool?

 

all help is appreciated, thanks x

A = 12 ( x+3)

    A = 12 ( 20 +3)       would mean width is   20+3 = 23  units
