Which of the following answers applies the Distributive Property of Multiplication Over Addition correctly for simplifying 23−9(2x+5)+11x

?

1 answer

The Distributive Property of Multiplication over Addition states that \( a(b + c) = ab + ac \). In order to apply this property to the expression \( 23 - 9(2x + 5) + 11x \), we will first focus on the term \( -9(2x + 5) \).

Applying the distributive property:

\[ -9(2x + 5) = -9 \cdot 2x - 9 \cdot 5 = -18x - 45 \]

Now we can substitute this back into the original expression:

\[ 23 - 9(2x + 5) + 11x = 23 - 18x - 45 + 11x \]

Next, we can combine like terms:

  1. For the \( x \) terms: \(-18x + 11x = -7x\)

  2. For the constant terms: \(23 - 45 = -22\)

Therefore, the simplified expression is:

\[ -7x - 22 \]

Thus, the use of the Distributive Property correctly simplifies the given expression to:

\(-7x - 22\)
