See below

Step-by-step explanation:

ΔABC has been flipped over, so we have a reflexion using line BC

So, the answer to 1.  is line BC

The result is ΔE'F'D'

Now ΔE'F'D' is moved 4 units to the right.  That is the answer to 2.

The result is ΔE"F"D"

Finally ΔE"F"D" is moved 1 unit down.  That is the answer to 3.

The final result is ΔEFD

Ok.  Did that help you?

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
