A rectangular skateboard park has an area of x^2+15x+56 what are the possible dimensions

For this case we have the following expression:

x ^ 2 + 15x + 56

We can factor this expression to find the possible dimensions of the rectangle.

Factoring we have:

(x + 7) (x + 8)

Answer:

the possible dimensions are:

(x + 7) * (x + 8)
