The intersecting chords theorem states that whenever two chords intersect, the product of their pieces is constant.
So, in this case, we have

Plugging your values, we have

This equation has solutions
, but we can't choose
, because it would lead to

So, the only feasible solutions is 
I'd go with: D. clockwise 90 rotation; reduction

Answer:
-3x + 6
Step-by-step explanation:
-3(x - 2) to find the equivalent of this expression, we need to multiply inside the parenthesis with -3 (with both x and -2)
-3(x - 2 = -3x + 6 (two negative expressions multiplied results in positive)
