1. 2(-3) + 4
-6 + 4 = -2
2. -4^2 - 3
16 - 3 = 13
3. 2 (m + 2) + 4
2m + 4 + 4
2m + 8
2m = -8
m = -4
4. i forgot how to do this. sorry :'(
Since it is a hexagon and it has 6 sides (and we assume it is regular since it doesn't tell us otherwise) then the hexagon will have 6 lines of symmetry (:
9x - 5y = 29....when x = 1
9(1) - 5y = 29
9 - 5y = 29
-5y = 29 - 9
-5y = 20
y = 20/-5
y = -4 <==
So, 52-24=28. That means that the remaining books are nonfiction books. 28 is the answer.
Pretty sure I can't give you test answers
