4 of 4 questions
27m - 2
13m + 8
13m - 2
27m + 8

Explanation:

Step1: Remove parentheses

To remove the parentheses, we distribute the negative sign to the terms inside the second parentheses:
$(20m + 3) - (7m - 5) = 20m + 3 - 7m + 5$

Step2: Combine like terms

Combine the $m$ terms and the constant terms separately:
For the $m$ terms: $20m - 7m = 13m$
For the constant terms: $3 + 5 = 8$

Answer:

$13m + 8$ (corresponding to the option "13m+8")
