72%.  

Step-by-step explanation:

We have been given that a big movie theater had 1,200 seats. 864 of the total number of the seats were sold.

To find what percentage of the total seats were sold we will find 864 is what percent of 1200.

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
