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 :
