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
