First, you do the distributive property on:
4(2n+3)
You would get
8n+12
Then add the original part of the equation in (4n)
4n+8n+12
Combine like terms
12n+12 is the answer

Step-by-step explanation:
The formula to finding the hypotenuse of a right triangle is a^2+b^2=c^2. So since the longest side is the hypotenuse, the 82 in. is the hypotenuse. 18^2+80^2= 6724, then we square root it, square root of 6725 is 82.

Determine a pair with a proportional relationship
A proportional relationship is:
Where k is the constant of proportionality.
So, we have:
This means that for a pair to have a proportional relation, k must be -1/3.
This is true for (c).
Where:
So, we have:
