Answer:
i think i'ts D. (x +2)
Step-by-step explanation:
Answer: Absolutely Never. No. He didn't do it correctly. Don't you do it.
I have never seen that error on Brainly before, although while I was teaching, I saw it enough times that I could always bet my math classes that I would see that error 100 times by the end of term. I always promised a case of beer for their grad (which would have given them 1 beer each). I never had to pay. They always made the error 100 times as a class.
Micah CANNOT cancel across a plus sign when going from the numerator to the denominator. You have to be able to take an x^2 out of every term or no term. Micah is totally wrong. Don't, whatever you do, follow his example.
Here is the only condition which will permit you that kind of cancellation.

Now Micah can cancel out the x^2. That is the only condition that will work.

The surface area of music box is 384 square centimeter
<em><u>Solution:</u></em>
Given that,
Volume of cubed shaped music box = 512 cubic centimeter
To find: Surface area of music box
<em><u>The volume of cube is given as:</u></em>

Where, "a" is the length of side
Therefore,

Taking cube root on both sides,
![a = \sqrt[3]{512}](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%5B3%5D%7B512%7D)
![a = \sqrt[3]{8 \times 8 \times 8}\\\\ a = \sqrt[3]{8^3}](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%5B3%5D%7B8%20%5Ctimes%208%20%5Ctimes%208%7D%5C%5C%5C%5C%20a%20%3D%20%5Csqrt%5B3%5D%7B8%5E3%7D)


Thus length of side of cube is 8 cm
<em><u>Find surface area of cubed shaped music box</u></em>
<em><u>The surface area of cube is given as:</u></em>

Substitute a = 8 in above formula

Thus surface area of music box is 384 square centimeter
The boundaries:
x = 0, y = 8; y = 0, √x³ = = 8, x = 4


= π ( 64 x - 16 * 2 *√x^5 + x^4 / 4 ) =
= π ( 320 - 1024/5 + 64 ) =
179.2 π
