The given equation is,

Thus, option (C) is the correct solution.
 
        
             
        
        
        
Binomial formula is :

= 495 * 0.0256 * 0.0167961 =
= 0.21284 ≈ 0.213
Answer: 
C ) 0.213
 
        
        
        
I just added an answer to a question exactly like that. The answer would be 1, 361.2. To find area you need to multiply the base and height together. Just think, b*h=a. Base times height equals area. Good luck!
        
                    
             
        
        
        
(2x-3y=-4)-2(x+3y=7)
2x-3y-2x-6y=-4-14
-9y=-18
y=2, making x+3y=7 become:
x+6=7
x=1
So the solution to the system of equations is the point (1,2)
