What is the difference? x/x^2-16 minus 3/x-4

Step-by-step explanation:

We want to find the difference;

The first denominator can be rewritten as;

Therefore the least common denominator is

We collect LCD to obtain;

Expand the parenthesis to obtain;

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.
