Answer 1

One sec

Answer 2

im confused on this because there are 2 numbers on top and three on the bottom

Answer 3

just add both

Answer 4

2 - 9 = -7

2 + 2 = 4, 4 - 15 = -11

-7 ÷ -11 = 0.64

Answer 5

so I am actually kinda lost because the top would be -7 unless it wants you to leave the 2x and x2 alone

Answer 6

maybe....i dont know because sometimes these problems are like that.

Answer 7

is x2 \[x ^{2}\]?

Answer 8
