Step-by-step explanation:
Use double and triple angle identities:
sin(2x) + cos(3x)
2 sin x cos x + 4 cos³x − 3 cos x
You have zero terms in that equation. A term is when a number is connected to a variable. You have no variables.

Answer:
n=15
Step-by-step explanation:
5(n+1)=2n+20
U start by expanding the first term which will give you 5n+5
Then after that u collect like terms giving u
5n-2n=20-5
Finally u evaluate it giving u
n=15
