Problema Solution
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
A = (3x^2+7x+4ft)^2 = LW
A =( 3x^2+7x+4)^2 = (3x +4)(Width)
Other side = width = ( 3x^2+7x+4)^2 / (3x+4)
Width = other side = (x+1)(3x+4)/(3x+4) = x+1
Final answer: other side length is x+1
