Answer:
B
Step-by-step explanation:
trust me:)
4n is less then or equal to 13-3
f(5) = 6(5-2) = 18
-12m-6n
Let's break this down systematically
Start:
8m + 2n - 4(5m - 2n)
Use the distributive property
8m + 2n - <u>4(5m - 2n)</u>
8m + 2n - 20m - 8n
Match like terms <em>m </em>and <em>n</em>
8m - 20m = -12m
2n - 8n = -6n
<u>-12m-6n</u>
