Answer 1

I think it's B

Answer 2

Look at the factors of the numerator and denominator:

3*x (x + 2)
------------- and think which factors are the same and will divide out.
(x - 4)*(x + 2)

Exclude the value of x that would make the factor that divides out equal to 0.

Take a look at what is left after the division.

If there is a variable in the denominator, you will need to exclude any value of x that causes the denominator to be zero.

Answer 3

I agree with your answer of B.
