Answer:
In summation form 
Step-by-step explanation:
Within one hour, the first person gives a stack of flyers to six people and within the next hour, those six people give a stack of flyers to six new people.
So, in the first 5 hours, the summation of people that receive a stack of flyers not including the initial person will be given by 
6 + (6 × 6) + (6 × 6 × 6) + (6 × 6 × 6 × 6) + (6 × 6 × 6 × 6 × 6).
So, in summation form 
Therefore, Sigma-Summation Underscript n = 1 Overscript 5 EndScripts 6 (6) Superscript n minus 1, gives the correct solution. (Answer)
 
        
                    
             
        
        
        
Answer: Angle T is larger than angle S. So by the side opposite to angle to (side RS) is longer than the side opposite to angle S (side RT). Therefore, side RS is longer than side RT.

It would be 600 because there are 6 faces in a square prism(cube) so if each side is 10 then each face is 100 so 6 times 100 is 600
