Sydney shared a tweet with 3 of her friends. Within 1 minute, each of those friends sent the tweet to 3 of their friends. Sydney wants to know how many people would have seen the tweet after 4 minutes. She thinks of 3 ways to explain what is happening. Part A: Match the descriptions to the appropriate method, if applicable. Way 1: After 1 minute 9 people have seen the tweet, after 2 minutes 27 people have seen the tweet,... [ Select ] Way 2: Multiplying 3 each minute for 4 minutes would be the same as: 34 [ Select ] Way 3: Two friends share the tweet with 3 more friends each minute for 4 minutes, so she multiplies 3 by 4 l Select ] Part B: If this scenario was represented by the function f (x), then f (3) = 27. What does this mean in terms of this scenario? [ Select ]

The pieces moved in set ways, and the purpose of the game was to move your pieces to trap the King piece of the other player. As you have probably figured out, Sessa invented chess. His king was utterly delighted at the game - war without bloodshed! - and asked Sessa what he would like in return. In the ancient bombastic style, the King said the request could include up to half of his kingdom. (That was not meant literally.) Sessa asked for the game board to be brought before him.
