12, 2, 4, and 7. The coefficients in the expression 12xy³+2x⁵y+4x⁵y²+7x⁵y are 12, 2, 4, and 7.
In order to solve this problem we have to know that the coefficients is a factor  linked to a monomial. For example, the first monomial of the equation is 12xy³ the coeffcient of xy³ is 12.
 
        
                    
             
        
        
        
Answer:
-18
Step-by-step explanation:
Essentially the same as (-6) - 12
 
        
                    
             
        
        
        
<span>5×(2-x)+9-7x
=5</span>×2-5<span>×x+9-7x
=10-5x+9-7x
=10+9-(5x+7x)
=19-12x
That's your solution. ^_^</span>
