C.
A doesn't work because x + x + x = 3x, not x^3.
B doesn't work because 14x + 10 - 2x has like terms, 14x and -2x can be combined, bit when you do so you get 14x - 2x, or 12x + 10. (So not 16x + 10)
D doesn't work because 12x^2 + 5x + 10 doesn't simplify; it can only be factored, and you cannot combine 12x^2 and 5x because their variables have different powers.
C, however, works fine. All they did is factor out a 3; if you distribute that 3 again, you get 12x + 16x back, so the two are equal.

i actually have the same question
Step-by-step explanation:
Answer:
(-2, 11/2)
Step-by-step explanation:
use the mid-point formula!
((x1+x2)/2, (y1+y2)/2)
((-1+-3)/2, (-1+12)/2)
(-2, 11/2)
