We are given a right triangle and we are asked to determine the hypotenuse given the measure of its sides. To do that we will use the Pythagorean theorem:

Now, we solve the square:

Now, we add the values:

Now, we take the square root to both sides:
![h=\sqrt[]{500km^2}](https://tex.z-dn.net/?f=h%3D%5Csqrt%5B%5D%7B500km%5E2%7D)
Solving the operations:

Therefore, the length of the hypotenuse is 22.361 kilometers.

3x (x^2+6x+9)
3x (x+3). (x+3)
3x. (x+3)^2
28,500 x 118
Then multiply that answer by 8% then add it to your total amount hope that helped you.

This is most relevant to spending habits. This would be where people would be spending money on a lot of different things and where their spending habits would show. It'd make the most sense to survey people there.
