Answer:
(0.91)^{20}(0.09)
Step-by-step explanation:
 
        
             
        
        
        
V=2 bc when u distribute the 6 to the numbers in the parenthesis u get 30-48v+12=54 then u subract 12 on both sides getting 30-48v=-66 then u subtract 30 on both sides making it -48v=-96 and mental math leads to -48•2=-96
        
                    
             
        
        
        
The initial expression is:
2x + 4(x - 2)
Replacing x by 3, we get:
2(3) + 4(3 - 2)
6 + 4(1)
6 + 4
10
The value of the expression is 10
 
        
             
        
        
        
565.487 units cubed
