Jon and lexi are playing a marble game. according to their rules, 4 point are awarded for each red marble collected and 3 point are awarded for each blue marble collected. which expression represents jon's total score if he has r red marbles and b blue marbles?

1.) 4r - 3b
2.) 2r - 3b
3.) 4r + 3b
4.) 7rb

the answer is d. 75%

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.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
