Answer:
-5/2 (I think)
Step-by-step explanation:
went up 5 and left 2 and from (-1,-5) and since i went left it is negative
 
        
             
        
        
        
(3a^4 * b^-2) * (2a^7 * b^-1)
= 6*a^(4+7)*b^(-2-1)
= 6*a^11*b^-3
        
             
        
        
        
Answer:
y=65
x=50
Step-by-step explanation:
exterior angle of a triamgle is equal to sum of two interior angles 
so
2y=130(as it is isosceles triangle)
y=65
we know y+y+x=180(sum of all angles of triangle)and (vertically opposite angle)
therefore, x=50
