1 answer

To apply the Distributive Property of Multiplication Over Addition correctly, let's simplify the expression \(23 - 9(2x + 5) + 11x\).

  1. First, apply the distributive property to \(9(2x + 5)\): \[ -9(2x + 5) = -9 \cdot 2x - 9 \cdot 5 = -18x - 45 \]

  2. Now substitute this back into the original expression: \[ 23 - 18x - 45 + 11x \]

  3. Combine like terms: \[ 23 - 45 = -22 \] \[ -18x + 11x = -7x \] So, the simplified expression becomes: \[ -22 - 7x \]

Now, let's analyze the responses:

  1. Response 1: \(23 - 18x - 45 + 11x\) - This is a valid simplification immediately after applying the distributive property.
  2. Response 2: \(14(2x + 5 + 11x)\) - This incorrectly groups the terms.
  3. Response 3: \(23 - 7x - 4 + 11x\) - This is incorrect as it misrepresents the final simplified form.
  4. Response 4: \(14(2x + 5) + 11x\) - This incorrectly splits the terms.

Therefore, the correct response that applies the Distributive Property of Multiplication Over Addition correctly and simplifies properly is:

Response 1: \(23 - 18x - 45 + 11x\).
