Let's break down the expression \(-3(2x + 7)\).

  1. The operations involved in this expression are multiplication and addition (since we are distributing the \(-3\) across the expression inside the parentheses).

  2. To simplify the expression, we will use distribution. This means we will multiply \(-3\) by each term inside the parentheses:

    \[ -3(2x) + (-3)(7) = -6x - 21 \]

So, filling in the responses:

  • This expression involves these two operations: multiplication and addition.
  • We will use the distribution to simplify this expression.
  • The simplified expression looks like: -6x - 21.
