which of the following are solutions to the quadratic equation check all that apply 2x ^ 2 + 6x - 10 equals x ^ 2 + 6

c and F

Step-by-step explanation:

2x² + 6x - 10 = x² + 6

2x² - x² + 6x - 10 - 6 = 0

x² + 6x - 16 = 0

(x + 8)(x - 2) = 0

x = -8

x = 2

so C and F

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
