First, let's factor both of these numbers.
256x:

144x:

Both of these numbers contain

, so that would be the greatest common factor. This could also be written as 16x.
Answer:
Corresponding angles theorem.
Step-by-step explanation:
The corresponding angles theorem states that corresponding angles are congruent.
Pretty much means that every other angle is congruent if two lines are parallel and a line traverses them.
Answer:
Step-by-step explanation:
y = ax² + bx + c
Plug the points into the equation to get a system of 3 equations with 3 unknowns a, b, and c.
-27 = 4a - 2b + c
-42 = 9a + 3b + c
-12 = a + b + c
(a,b,c) = (-4,1,-9)
y = -4x² + x - 9
I believe it is D, because if you divide 2/6 its .333 minus 1.25/6, which is .124.
