match each step with the property used to get to that step. (note: the column that lists the algebraic expressions is already in the correct order.)

(6x + 3) - 5x

1. (3 + 6x) - 5x
2. 3 + (6x - 5x)
3. 3 + (6 - 5)x
4. 3 + (1)x
5. 3 + x

subtraction

step-by-step explanation:

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.
