Answer:
-16b - 20
Step-by-step explanation:
First, we'll need to simplify 3(-2b - 10)
3 * -2b = -6b
3 * -10 = -30
Then we rewrite our expression like this:
-6b - 30 - 10b + 10
Now, we rearrange the expression so that the like terms are next to each other.
-6b - 10b - 30 + 10
Then, we simplify
-16b - 20
Hope this helps!
