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.

Answer:
Of(x) =100(5) I think cause its gonna equal 500
\/(5x) = x\/5
[\/(5x]² = [x\/5]²
5x = 5x²
5x²-5x = 0
5x(x-1) = 0
5x = 0 --> x = 0
x-1 = 0 --> x = 1
