Problema Solution
Essay: Show all work. The area of a rectangular swimming pool is given by 3x^2+7x+4ft^2. One side length of the pool is given by 3x + 4 feet. What is an algebraic expression for the other side length of the pool? Simplify this, and include correct units as part of your answer.
Answer provided by our tutors
The other side is y
The area = y*(3x+4) = 3x^2+7x+4
y = 3x^2+7x+4/(3x+4) = (3x+4)(x+1)/(3x+4) = x+1
So
The other side is (x+1) ft
