X + x + x = 15 find the x

5

5 + 5 = 10

10 + 5 = 15

Step-by-step explanation:

x+x+x=15

Combine Like Terms:

3x=15

Divide by 3 to isolate x:

x=5

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!
