What does it mean to isolate the variable? А: Evaluate the coefficient.

B: Reverse the inequality sign.

С: Get zero by itself on one side of the inequality sign.

D: Get the variable by itself on one side of the inequality sign.

D

Step-by-step explanation: get the variable by itself on one side of the inequality sign.

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

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)
