Jana has a sandbox that is 4 1/2 feet long, 5 feet wide, ad 1/2 feet wide, and 1/2 foot deep. How many cubic feet of sand does she need to fill the sandbox completely

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

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
