Let's analyze the expression -3(2x + 7).

  1. The expression involves the operations multiplication and addition (since we are multiplying -3 with the terms inside the parentheses).
  2. We will use the Distributive property to simplify this expression.
  3. The simplified expression looks like -6x - 21.

So, filling in the blanks:

  • This expression involves these two operations multiplication and addition.
  • We will use the Distributive property to simplify this expression.
  • The simplified expression looks like -6x - 21.
are you sure this is correct

Let's clarify and break down the process step by step for the expression -3(2x + 7).

  1. Identify the Operations: The expression -3(2x + 7) indeed involves:

    • Multiplication (because we are multiplying -3 by each term inside the parentheses)
    • Addition (because inside the parentheses, we have the expression 2x + 7, which involves addition).
  2. Applying the Distributive Property: The Distributive Property states that a(b + c) = ab + ac. Applying this to our expression:

    • We multiply -3 by each term: \[ -3(2x) + -3(7) = -6x - 21 \]
  3. Simplified Expression: After applying the Distributive Property, we get:

    • -6x - 21

So, completing the sentences using these components:

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

Thus, my previous response was correct. Thank you for your patience!
