If each of the 254 students who perform on stage has 3 friends come to see the musical, and each of the 137 students working back stage has 2 friends come to see the musical, how many total audience members will there be?

Okay so all you have to do is multiply 254 by 3 and get  762.                                          Then multiply 137 by 2 and get 274.                                                                                           Lastly, add 762 and 274 together and get 1036.                                                                    So you answer is 1,036 audience members are attending.

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.
