Answer this.Please

x -22

Step-by-step explanation:

Sum = -7            (-22+15 = -7)

Product = -330   (-22*15 = -330)

Factors = -22 , 15

x² - 7x - 330 = x² +15x - 22x - 22 *15

                    = x(x + 15) -22(x + 15)

                   = (x +15)(x -22)

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.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
