the area of a rectangular swimming pool is given by 3x^2+7x+4 ft^2.
One length of the pool is given by 3x+4 ft. what is an algebraic expression for the other side length of the pool?
Simplify this and include correct units as a part of your answer
:
to find the other side, divide the area by the known side
:
%283x%5E2+%2B+7x+%2B+4%29%2F%283x%2B4%29
Factor
%28%283x%2B4%29%28x%2B1%29%29%2F%283x%2B4%29
Cancel out (3x+4), leaving us with
x+1 is the other sides of the pool
