Answer:

n=5-2p

Step-by-step explanation:

STEP 1: <em>Rewrite the equation as  3 n + 6 p = 15 .</em>

3n+6p=15

STEP 2: <em>Subtract  6 p  from both sides of the equation.</em>

3n=15-6p

STEP 3: <em>Divide each term by  3  and simplify.</em>

n=5-2p

Not sure what 14 is asking?

15 would be 16.

The square root of width squared plus length squared equals the diagonal.

So if you just change the order of the equation you can find the length.

Double check it by doing it both ways to see if your answer is right.
