Amultiple choice test contains 10 questions there are four possible answers for each question. how many ways can a student answer the question?

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

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
