Answer 2

13c part is correct

but what is -6d - 3d = ?

Answer 3

-3

Answer 4

umm no

-6 -3 = -1(6+3) = ?

Answer 5

why would we subtract those ?

Answer 6

I dont understand

Answer 7

-6 -3

factor out -1 so you can see the final answer

-6 = -1 x 6
-3 = -1 x 3

-6 - 3 = -1(6) + (-1)(3) = -1(6+3) = ?

Answer 8

start at -6

Answer 9

then go 3 units to the left (we go 3 units left because we're subtracting 3)



so that's why `-6 - 3 = -9`

Answer 10

I got -9d

Answer 11

correct :)

Answer 12

would the final equation be 13c+-9d?

Answer 13

so your answer would be

13c - 9d

not 13c + 9d
