Answer:
3 +2xy+6xy+12x+4y
+2xy+6xy+12x+4y
Step-by-step explanation:
(3x+y)(x2+2y+4=+2xy+6xy+12x+4y
 
        
                    
             
        
        
        
we have to find equation similar to 

Firstly , we can divide both sides by 2


now, we can multiply both sides by 3

we get

The answer is 0.675. 2700:4000 is a ratio that can be expressed as 2700/4000 = 27/40 = 0.675 
        
             
        
        
        
2y - 3x = 4 
2y = 3x + 4
y = 3/2*x + 2
y = kx + b ==>
k = 3/2 = 1,5
