-7

To evaluate the expression 5x3 + 2 for x = -1, you need to substitute the value of x with -1 in the expression and perform the arithmetic calculations:

5(-1)^3 + 2

First, calculate (-1)^3, which means raising -1 to the power of 3:

(-1)^3 = -1 x -1 x -1 = -1

Now substitute this value back into the expression:

5(-1)^3 + 2 = 5(-1) + 2 = -5 + 2 = -3

So the answer is -3.

Therefore, the correct answer is B) -3.
