Step-by-step explanation:
The question is incomplete, as the 8 expressions are not given.
The general explanation is as follows
As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.
Then you categorize each result, depending on if it equals
or not
Take for instance:

Using law of indices:

---- equivalent

Factorize the numerator


Cancel out 2

Apply law of indices


---equivalent

Express as exponent

Apply law of indices

---- equivalent

Solve exponents

---- not equivalent
I think it’s B. 4 because 65 divides by 15
Answer:

Step-by-step explanation:
Factor the expression to give you the result, or you can use the quadratic formula and notice you get 3 and 6.
Answer:
f(x)=-4x^2-6x-1
g(x)=-x^2-5x+3
(f+g)(x) = (-4x^2-6x-1) + (-x^2-5x+3)
-4x^2 - 6x - 1 -x^2 - 5x + 3
= -5x^2 - 11x + 2
