Answer:
8. 24+36+12= 72 in cubed
And yes it would fit because 72 is greater than 64
9. 2+21= 23 ft cubed
 
        
             
        
        
        
The simplified expression for 6(2( y + x)) is 12y + 12x.
Accordin to the given question.
We have an expression 
6(2( y + x))
Therefore, 
The simplified expression for 6(2( y + x)) is given by 
6(2(y + x))
= 6(2y + 2x)          (by distributive law)
= 12y + 12x              (by distributive law)
Hence, the simplified expression for 6(2( y + x)) is 12y + 12x.
