Four more than twice a number x is 12. write an equation that represents this situation. determine the number x

2x+4=12

x=4

Step-by-step explanation:

Let's look at the way that this question is written in order to write the equation

"Four more than" this means that we need to add 4 to the next thing that is listed.

"Twice a number x" means 2x

Combining the last two gives us 2x+4

"Is 12" means =12

Combining everything gives us

2x+4=12

Now we can solve for x

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!

mean, 40.6
