What is x ? and how do you get it ? me plz

X is -8

To solve the problem you have to get X by itself. So you would multiply every number in the equation by 4. Which will give you -X + 12 = 20

Now you have to subtract 12 on both sides of the equal side giving you -X = 8 since the positive twelve cancels out.

Finally you divide by negative 1 since X can NOT be a negative!

Your final answer should be X = -8

I hope that helped and you know what to do now...

x/4+3=5

     -3   -3

x/4=2

4(x/4)=(2)4

4x=8

x=2

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!

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
