Emily is a diver. Today she descended to a depth of 40 feet. Then, she ascended 10 feet. Next she descended 24 more feet. After doing this, what was her depth?

54 feet

Step-by-step explanation:

If she stars at 0 feet, 0+40=40.

40-10=30.

Subtract 10 because Emily ascends 10 feet.

Then, 30+24=54

So now, her depth is 54 feet

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
