Answer 13

did you see the anwser

would you like me to explain or no

Answer 14

Yes an explanation would be nice.

Answer 15

Simplifying
1 + cos(8x) = 0

Remove parenthesis around (8x)
1 + cos * 8x = 0

Reorder the terms for easier multiplication:
1 + 8cos * x = 0

Multiply cos * x
1 + 8cosx = 0

Solving
1 + 8cosx = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + 8cosx = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 8cosx = 0 + -1
8cosx = 0 + -1

Combine like terms: 0 + -1 = -1
8cosx = -1

Divide each side by '8osx'.
c = -0.125o-1s-1x-1

Simplifying
c = -0.125o-1s-1x-1

Answer 17

no you must symplify not solve

Answer 18

This is trig not algebra

Answer 19

take the anwsers and do the distributive property
