Answer: 27a^3
It is 27a^3 because if you do 3×3=9 then 9×3= 27
We can get two different equations from this:
3x = 18
and
3x = -18
So:
x = 6, x = -6
x = {6, -6}
12(3w+8)=25
36w+96=25 ( I used the distributive property)
-96 . -96
36w=-71
w=-1.972222.... ( I divided both sides by 36)
51.36 is the answer.
The equation is total=original(1+% in decimal form)
8x^2*3xy
24x^3y I believe. Sorry if I’m a little rusty
