How do I find out if this is an infinite solution
4(x-2) + 7 = 4x - 1

x = all real numbers, infinite solutions

Step-by-step explanation:

4(x-2) + 7 = 4x - 1

Distribute

4x -8+7 = 4x-1

Combine like terms

4x -1 = 4x-1

Subtract 4x from each side

4x-1 -4x = 4x-1-4x

-1 = -1

This is always true so  there are infinite solutions for x

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.
