D. 16

Step-by-step explanation:

$GH^2 = GF \times GE$

$12^2 = 9 \times (9+x - 2)$

$144= 9 \times (7+x)$

$\frac{144}{9}= (7+x)$

16= 7+x

16-7=x

9=x

GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2

GE = 16

It needs permutations of the order does matter, like 3 people ordering from a coffee shop to see who goes first.

Combinations are when the order doesn't matter, like if you had 3 numbers behind your back and you had to guess the 3 not in order

It needs neither when you don't need to find the amount of choices you have (or something similar) for something
