Is 3+x=x+3 infinite, one solution, or no solution

Infinite solutions

Step-by-step explanation:

If we subtract 3 from both sides we get:

x = x

If we subtract x from both sides of that, we get:

0 = 0.

Well... 0 is ALWAYS equal to 0, so there is no answer that can make that statement invalid, meaning that all numbers are solutions.

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.
