Answer:
The correct answer is Option 3: 12y
Step-by-step explanation:
A polynomial term is usually made of a variable and a co-efficient.
Like terms are those terms that have the same variables i.e. x and 44x are like terms.
Given expression is:

All the terms have only y which means that all three terms are alike.
The coefficients of like terms are added or subtracted according to their sign.
= 12y
Hence,
The correct answer is Option 3: 12y

Answer:
g[f(-2)] = 7
Step-by-step explanation:
f(x) = x^2
g(x) = 3x – 5
g[f(-2)]
First find f(-2) = (-2)^2 = 4
Then find g(4) = 3(3) -5 = 12-5 = 7
