This expression involves these two operations Response area and Response area .

We will use the Response area to simplify this expression.

The simplified expression looks like Response area .

Answer 1

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**.
