Part A: Write an algebraic expression for 4 more than 3 times a number. Part B: Write a verbal expression for 2(n + 9). (5 points)

((urgent))

Part A: 4+3x

Part B:  two times the sum of a number and nine

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.
