Answer:
70 + 4D
Step-by-step explanation:
- (2 x 100) + (7 x 10) + (4 x D) + (2 x 100)
    - (200) + (70) + 4D + 200
        -200 + 70 +4D + 200
              -130 + 4D + 200
                    70 + 4D
 
        
             
        
        
        
Answer:
2x^2+16x-66
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last) 
(2x-6)(x+11) 
F- 2x*x=2x^2 
O-2x*11=22x
I--6*x=-6x 
L--6*11=-66 
2x^2+22x-6x-66 
Combine like terms 
2x^2+16x-66
