Answer:
sum of the polynomials is 
Step-by-step explanation:
Given polynomial is (7 x^3– 4 x^2) + (2 x^3 +3 x)
adding x^3 terms, now we get 


Therefore the sum of given polynomial is 

 
        
             
        
        
        
The solution must be larger than 9, because the answer is h=10
