Answer:
7.16
Step-by-step explanation:
When simplified:
8x^2-8+3x^2+6x
= 11x^2+6x-8
Therefore, the answer would be 3 terms... C.
Answer:
The proof is given below.
Step-by-step explanation:
Given: ( the correct question and ans is as follow )
sin (x + y) = 3sin ( x - y)
To Prove
tan x = 2 tan y
Proof:

Using the identities

we get

Now we will take sin x . cos y to the left hand side and cos x . sin y to the right hand side,we get
