Answer:
John is 20 years old.
Step-by-step explanation:
Given the second mean is 18, it is equal to the first mean age plus John's unknown age. The sum is also divided by 2 because there are 2 values in the sum (1. John's age and 2. the mean, 16 yrs old).
Set up an equation: ![\frac{x+16}{2}=18](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B16%7D%7B2%7D%3D18)
multiply both sides by 2: ![x+16=36](https://tex.z-dn.net/?f=x%2B16%3D36)
simplify: ![x=20](https://tex.z-dn.net/?f=x%3D20)
I’m pretty sure it would be equilateral because all the sides are the same:)
