Answer:

1.) Add -15 and 9.

Explanation:

We have been given an expression
(-2)^3+4/ (-15+9)(3)-4. We are asked to choose the correct step to evaluate our given expression.

We will use order of operations PEMDAS to solve our given problem.

P = Parenthesis,

E = Exponent,

M/D = Multiplication or division (from left to right).

A/S = Addition or subtraction (from left to right).

So, first of all, we need to remove parenthesis. To remove parenthesis, we have to add -15 and 9, therefore, 1st option is the correct choice.
