The equation -2(3w-7)=-4 is solved in several steps below for each step choose the reason that best justifies it.

hi how are you doing today, if you need just ask me.

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

you would 18 *0.25 = 4.5
