Answer:

384 inches²

Step-by-step explanation:

The surface area of a cube is found by using 6a².

6 = the number of sides in a cube

a = the given dimension (in this case, 8 inches long)

SA = (6)8²

SA = 6(64)

SA = 384

Hope this helps, sorry if it’s not what you’re looking for :)

The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend?
velikii [3]

By subtracting the given addend to the sum, we see that the other addend is:

6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8

<h3>How to get the other addend?</h3>

We know that the sum of two polynomials is:

8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9

One of the addends is:

2d^5 - c^3d^2 + 8cd^4 + 1

To get the other addend, we can subtract the given addend to the sum:

8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9 - (2d^5 - c^3d^2 + 8cd^4 + 1)\\\\6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8

Then we can conclude that the other addend is:

6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8
