Morales's class? *

9 Boys in the classroom.

Step-by-step explanation:

3:7 is the ratio of boys to girls.

This is taking into account only 10 of the students of a 30 student class.

You have to times the ratio by 3 making it 9:21

Therefore, there are 9 boys and 21 girls.

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
