Answer:

Step-by-step explanation:
We have the two functions:

And we wish to find:

First, let’s find f(2) first. So, we will substitute 2 for x for f(x):

Hence, we can now substitute 3 for f(2):

Now, we can find g(6). Substitute 6 for t for g(t):

Therefore:

Triangle A is an Isosceles
Triangle B is Equilateral
Triangle C is Scalene
A is 3
B she can pick 2 by 2
3/4, 7/6, 11/12
