N=199 because in order to get a a smaller negative you would have to add a positive into a negative
The hardest math problem is solving life, I mean this because everyone is trying to make good decisions which means you never stop thinking through your whole day
1.) -8 + 10(6 + 4r)
First multiply the 10 into (6 + 4r)
-8 + 60 + 40r
52 + 40r
2.) (8m² - 8m + 8) - (2m - 7m² - 6)
Distribute the - into (2m - 7m² - 6)
8m² - 8m + 8 - 2m + 7m² + 6
Combine like terms
15m² - 10m + 14
(idk if you need to factor this or if you can leave it as is)
