The area of a rectangular swimming pool is given by 4x^2+19x+12 ft one side length f the pool is given by 4x+3 feet. What is an algebraic expression for the other side of lenght of pool? Simpily this, and include correct units as part of your answer.

A = Area
L = Length
W = Width
A = 4 x ^ 2 + 19 x + 12
L = 4 x + 3
A = L * W
W = A / L
W = ( 4 x ^ 2 + 19 x + 12 ) / ( 4 x + 3 )
W = x + 4
P.S
If you don't know how to divide that two exspression go on:

When page be open in first rectangle tape :
4 x ^ 2 + 19 x + 12
In second rectangle type :
