B1=4,b2=8,h=2
pls help

okay wait before i answer, is this for your points on a graph?

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

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong
