Answer:

B

Step-by-step explanation:

The area of the Sandbox is given as x^2 + 3x

You are also given that the width of the sandbox is x

The question is, what is the length

Formula

Area = L * w               Substitute the givens into the formula

x^2 + 3x = L * x          Use the distributive property to put brackets on left.

(x^2 + 3x) = L*x         Pull out the common factor on the left.

x(x + 3) = L * x            Divide both sides by x

x(x + 3)/x = L*x/x

x + 3 = L
