The y of (-6,-7) is -7 so the equation must be y = -7
 
        
             
        
        
        
Add all and divide by how many there is 
answer is 5.08
        
             
        
        
        
The formula to find area would be length times height times width. In number six, the prism is 12 cm in length, 9 cm wide, and 5 cm high. So your equation would be 12 x 5 x 9. Your answer would be 540 cm squared.
Don't know about number seven, though
        
             
        
        
        
I believe it’s -12x but I may be wrong I hope this helped!
