Which expression is represented by the phrase"the square of x increased by the product of 8 and x a. x^3 + 8 - x b. x^2 + 8x c. x^2 + 8 - x d. x^3 + 8x

"The square of x" means x^2, so we can eliminate options A and D.

"product of 8 and x" means that 8 and x are multiplied together (like 8x)

If x^2 is increased by 8x, we are adding x^2 and 8x together.

B. x^2 + 8x
