Question 184441
The owner of a daycare center plans to have a rectangular sandbox built in the outdoor play area. The width (in feet) of the sandbox is given by the polynomial 2x-5. If the length of the sandbox is designed to be 10 feet longer than the width, write a polynomial that represents the area of the sandbox.
--------------
W = 2x+5
L = W + 10 = 2x+15
Area = L*W
Area = (2x+5)*(2x+15)
Area = 4x^2 + 40x + 75 square feet
