In the first round of a game, cheyenne tells a joke to 5 people. in the second round, those 5 people each tell the joke to 5 more people. if the pattern continues, which expression shows the number of people who will be told the joke in the sixth round?

First round: 5 people are told
Second round: 25 people are told

Square each number.
The second round is 5 squared, so the third round will be 5 to the third, or 25 squared.

So the answer is 15,625

15,625 hope it helps

Lets see what we're working with here

-18(s) + 24 - [-9] (s) = ?

Take out your "like terms" 
  -9(s) + 36

First,  we have to 'solve' the number -9 which is equal to 0

Solve this one too (only if you want to it to make it easier) (s) - 4 = 0
         We have to add a positive four to your sides (+4)

We have found one solution in this equation

The value of "S" is 4
