The first step is to solve (x plus 3) since we use the PEMDAS when solving equations. We go in order of letter. P stands for parentheses which is the first step to solve.
In this type of questions, you just need to plug in the numbers you are given. But don't forget to put parentheses around negatives and use them wherever you want to clarify the equation.
Now let's take the exponents first:
Then do multiplications:
Then add plusses and minuses:
So the answer is -17.
Did you not include D or finish writing D since the first three are not right. If one of the possible answers is that they are alternate exterior angles or the same degrees, that would be the answer.
