4 walls

Step-by-step explanation:

First we could re-write 3 gallons with a denominator of 4 which would be 12/4 gallons. Next, we could divide like so:

12 divided by 3 = 4

Our answer is 4 walls

Hope this Helps!!! :)

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
