Ineed a halloween costume idea for a group of eight grade girls

Well, although this does not fit in the mathmatic category, I will still throw out some ideas for you.

- All dress up like Minions

- If your into it, you could all dress as superheros.

- All go as a different flavor of LaCroix (Costumes can be bought online)

- Try all going in color matching suits.

- All go as disney characters.

The list goes on :) Hope I helped a tad!

depends on how many days you are talking about

step-by-step explanation:

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
