|x| + 10 = 1 a. x=9
b. x= 9 or x = -9
c. x=0
d. no solution ANSWER

Explain why?

|x| + 10 = 1

|x| = -9

D/No solution

An absolute value can't be negative.

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.
