The area of a rectangular swimming pool is given by 5x^231x28ft^2. One side length of the pool is given by 5x + 4 feet. What is an algebraic expression for the other side length of the pool?

Area of a rectangle = length * width
therefore:
5x^231x28 = (5x + 4)* the other side
or
The other side
= (5x^231x28)/(5x+4)
= (5x+4)(x7) /(5x+4)
= x7
