Please help find the inequalities

I and III

Step-by-step explanation:

5x - 10 - 5 <=>

5x 5 <=>

x 1

For I:   -1 1   Correct

For II:   9 1   False

For III:   1 1   Correct

Hence, I and III is the final answer.

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.
