Answer:
B
Step-by-step explanation:
If you look at A and you subtract 3x by 4x you get x and you subtract 3 from -7 and you get -10. But if you look at B you do the stuff in the parentheses first and you get 4x+12x+28=16x+28 and they're the same so it's B.
It would be: (2/9)² = 4/81
In short, Your Answer would be Option A
Hope this helps!
