Answer:

12x = 0

Step-by-step explanation:

5= 5+2x

Subtract 5 from each side

5-5= 5-5+2x

0 = 2x

Multiply each side by 6

0*6 = 2x*6

0 = 12x

Answer:

12x = 0

Step-by-step explanation:

Let's first find x:

5 = 5 + 2x

Subtract 5 from both sides. Since both sides are equal, subtracting the same from each side will still leave both sides equal.

5 = 5 + 2x

5 - 5 = 5 + 2x - 5

Since 5-5 = 0:

0 = 5 + 2x - 5

0 = 5 - 5 + 2x

Again, 5-5 = 0:

0 = 0 + 2x

0 = 2x

Dividing both sides by 2:

0/2 = 2x / 2

0 = x

x = 0

As we can see, x = 0.

Thus, 12x must also be 0:

12x

Putting in x = 0:

12 * 0 = 0

Answer: 12x = 0

A sphere has a volume of V=900 in cubed. What is the surface area?

ycow [4]

First, we must solve for the radius of the sphere:
V= $\frac{4}{3}$ $\pi$ $r^{3}$
r=(3 $\frac{V}{4 \pi }$ ) $^{ \frac{1}{3} }$
r=(3* $\frac{900}{4 \pi }$ ) $^{ \frac{1}{3} }$
r≈5.99

Second, we must solve for surface area:
A=4 $\pi$ $r^{2}$
A=4* $\pi$ * $5.99^{2}$
A≈450.88 $in^{2}$
