Please help! It’s been due since yesterday!

1 student

Step-by-step explanation:

We know that groups of 3 cannot equaly fit into 25. So we have to think about what number less than 25 can have three equally divided in it. The number is 24. Now we know that 8 groups of 3 people can greet the parents. One student cannot be on the team becuase there are 25 students and 24 of them are already in groups. 25-24=1.

You could also use division and get 1 as the remainder: 25 ÷ 3 = 8 with 1 as a remainder

I hope I helped! Let me know if you need help :)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
