Answer: 9) 15m-30
11.) 5b-5
Explanation:
With Distributive Property, you are basically looking at the question like this: (5*3)m +(5*-6)
When you take a negative and multiply it with a positive it will be a negative number.
it would then get simplified as
15m-30
Same with number 11. look at it as
(5*1)b +(5*-1)
again a negative and a positive gets you a negative so your answer would be
5b-5
