Answer:
if i got you question right then its x=(-13/7) x=(-3/(2+b))
Step-by-step explanation:
to find the roots you need to make it equal to 0. 
(x+6x+13)(2x+bx+3) =0
(7x+13)((2+b)x+3) =0 
now there are 2 cases:
-> 7x+13=0 7x=(-13) x=(-13/7) solved
-> (2+b)x+3=0 (2+b)x=(-3) x=(-3/(2+b)) solved
 
        
             
        
        
        
Answer:
4
Step-by-step explanation:
(A+B+C+D) / 4 = 10 .... average=sum/number of item
(A+B+C)/3 = 3D ... average of first 3 (A,B,C) is triple of forth (D)
A+B+C = 9D
(9D+D)/4=10
10D = 40
D = 4
