<em><u>Answer:</u></em>
I'm assuming this is a <em>combining like terms</em> question, in which case the answer would be 6n - 3c.
<u><em>Step-by-step explanation:</em></u>
I'm guessing your teacher wants you to combine the like terms, and 1n plus 5n = 6n, minus 3c is the answer, which is 6n - 3c. If your teacher wanted you to solve for each variable, you can't do that because you don't have enough information, and there's an infinite number of solutions.

Answer:
Step-by-step explanation:
The volume of a cube.
The formula is V = s^3 where is the the "whole side length" of the cube. The cube requires three dimensions be multiplied together to find its volume.
That's why the formula is written as V = s^3. It means that V = s * s * s which is three sides multiplied together. They also need to be at right angles to each other.
