The answer is a 36
This is because if you take the area of one of the three triangles that make up the trapezoid you do 1/2 base times height and get 12 and you add all three together thus getting 36 square inches

Sequence: -4, 8, -16 
rate of increase: -16/8 = -2 
 
If you make A1 the first term in the sequence you must use (n-1) in the explicit formula. If you go backwards in the sequence to find A0 = 2 then you would use n. 
The don't have A0 = 2 listed as an option so we use A1 = -4 and (n-1) terms. 
An = -4(-2)^(n-1) 
Solving for the 5th term A5, use n = 5 
A5 = -4(-2)^(5-1)
A5 = -4(16)
A5 = -64 
So the answer is B. 
        
                    
             
        
        
        
Answer:
For question 2 (Triangle):
The triangle hThe entire triangle area = 2 * 13.125 = 
26.25 
 
Triangle perimeter both legs = 16.6 + base (7) = 23.6
For question 1 (Parallelogram): 
longer congruent sides = 6-0 OR 4-(-2) = 6units
area= 3×6 = 18units^2
