Philip and Laura want to build a pool in their backyard. The length and width of the pool can be represented by the equation
lakkis [162]

The area of Philip and Laura's pool is 3x^2 - 13x - 10 square feet

<h3>Area of a rectangle</h3>

Givene the dimensiion of Philip and Laura's pool as:

Length = (x - 5)

Width  = (3x + 2)

Given the area expressed as:

f(x) = (x - 5)(3x + 2)feet

Taking the product will give:

f(x) = 3x^2 + 2x -15x - 10

f(x) = 3x^2 - 13x - 10

Hence the area of Philip and Laura's pool is 3x^2 - 13x - 10 square feet
