To find the final term to compete the square you need to divide the 'x' term by 2 then square it
![x^2 +18x + = 44+ \\ x^2+18x+( \frac{18}{2} )^2=44+( \frac{18}{2} )^2 \\ x^2+18x+9^2=44+9^2 \\ x^2+18x+81=44+81 \\ (x+9)^2=125](https://tex.z-dn.net/?f=x%5E2%20%2B18x%20%2B%20%3D%2044%2B%20%5C%5C%20x%5E2%2B18x%2B%28%20%5Cfrac%7B18%7D%7B2%7D%20%29%5E2%3D44%2B%28%20%5Cfrac%7B18%7D%7B2%7D%20%29%5E2%20%5C%5C%20x%5E2%2B18x%2B9%5E2%3D44%2B9%5E2%20%5C%5C%20x%5E2%2B18x%2B81%3D44%2B81%20%5C%5C%20%28x%2B9%29%5E2%3D125)

Hey there!
To start, the mean of the answer is also known as the average value of a set of numbers. This is calculated by dividing the sum of the set by the total amount of numbers.
In this case the sum of all the numbers is 13 + 6 + 8 + 6 + 15 which is equal to 48.
Now, divide 48 by the total number of numbers in the set: 48/5 = 9.6
Your final answer should be 9.6, or you can leave it in fraction form as 48/5.
Hope this helps!
