The radius of Earth is about 6378 km, and the radius of Mercury is
       
      
                
     
    
    
    
    
    1 answer:
            
              
              
                
                
In this case, Earth and Mercury are both spheres. The formula for volume of sphere is 4/3(pi)(radius)(radius)(radius).
Since the volume of both is immense, it is hard to describe here. 
The concept to solve this problem would be to insert the appropriate radius length hence find the difference between the two spheres.

Answer is A 
7 + 2X = 2(X-1) + 4
7 + 2X = 2X-2+4
7 + 2X = 2X + 2 whether 2X = 2X-5  or 5 + 2X = 2X still  0 = 5 Or 0= -5 which is not possible
 
        
                    
             
        
        
        
        
Answer:
This is a triangular prism
Step-by-step explanation:
 
        
             
        
        
        
you need to distribute the 5. multiply each term in the parentheses by 5:
5(1) + 5(3x)
5 + 15x
