12. On addition, you can just combine like terms.
2v^3+(-v^3)=v^3
-v+v cancels each other out
8+(-3)=5
So you have v^3+5
14 On subtraction, you have to remember to distribute the negative sign so after you do that you have:
4h^3+3h+1+5h^3-6h+2
Then you can combine like terms
4h^3+5h^3=9h^3
3h-6h=-3h
1+2=3
So you end up with:
9h^3-3h+3

3 – x
21,000-600 = 20,400
20,400/3400 = 6
t = 6
21,000=3,400(6)+600
21,000=20,400+600
21,000=21,000
34.00
*6
__
204.00
3,400*6=20,400
