Answer:
w = 31
Step-by-step explanation:
To find the value of w:
  We know that the three angles in a triangle add to 180 degrees
w + w + (4w-6) =180
Add like terms
6w-6 = 180
Add 6 to each side
6w -6+6 =180+6
6w = 186
Divide each side by 6
6w/6 = 186/6
w = 31
 
        
             
        
        
        
Answer:
Step-by-step explanation:
sorry this one isnt an easy one. but your answr should be 1.8
 
        
             
        
        
        
Formula: n-2(180) 
n = number of sides
6-2(180) = 720 degrees
        
                    
             
        
        
        
If we expand bx to jx and kx we have:
5y^2-2y-7
5y^2-7y+5y-7  then factor...
y(5y-7)+1(5y-7)
(y+1)(5y-7)
So the other factor is:
(y+1)
