score: 2/4 penalty: 1 off
question
which expression is equivalent to 3w - 4 - w - 9?
answer
2w - 13 4w - 13
2w + 5 -w - 10

Explanation:

Step1: Combine like terms for \( w \)

Identify the terms with \( w \): \( 3w \) and \( -w \). Combine them: \( 3w - w = 2w \).

Step2: Combine constant terms

Identify the constant terms: \( -4 \) and \( -9 \). Combine them: \( -4 - 9 = -13 \).

Step3: Form the simplified expression

Combine the results from Step1 and Step2: \( 2w - 13 \).

Answer:

A. \( 2w - 13 \)
