Complete the following by applying polynomial identities to complex numbers. Show your work. Please help!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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.
