G(2)= -2-2
g(2)= -4
r(g(2))= r(-4)
r(-4)= 2(-4)^2 -1
r(-4)= 31
ANSWER=31
        
             
        
        
        
when you have 2 negative numbers you actually add the 2nd number to the first one
 example:
-4 - -2 =  becomes -4 + 2 = -2
 
        
             
        
        
        
Option A: SU, TU, ST is the right answer
Step-by-step explanation:
In a triangle
- The largest side and the largest angle are opposite to each other
- The shortest side and the shortest angle are opposite to each other.
So using the above axioms we can observe the triangle.
- The largest angle is m∠U = 80° so the side opposite to it is the largest i.e. ST is the largest
- The smallest angle is m∠T = 25° so the shortest side is SU 
- The third side will be the middle side as the angle ∠S is greater than 25° and less than 80°
So the sides in order from least to greatest are: SU, TU, ST
Hence,
Option A: SU, TU, ST is the right answer
