Answer 9

I think they want you to solve for all the letters

Answer 10

yes..

Answer 11

can you set up the next equation ?

Answer 12

oh ok I will try that

Answer 13

writing down the equation should be easy:

you have 2 to solve
-w^2 = -81
and
2f = -14

Answer 14

ok i got 2f=-14 = f=-7

Answer 15

yes. but I would write it as
2f = -14
f = -7
on separate lines. (not with the = between the 2 equations because it is confusing)

Answer 16

for
-w^2 = -81

this is the same as
-1 * w^2 = -1 * 81
one good first step is multiply both sides by -1
(or divide both sides by -1)
