Simplify and find the undefined values of

Given:

Given that the expression is

We need to simplify the value and determine the undefined value.

Simplification:

Let us simplify the given expression.

Factor out the term from the expression, we get;

Factor out the term from the denominator of the expression, we get;

Cancelling the common terms, we have;

Thus, the simplified expression is

Undefined value:

The undefined value of the expression is

Thus, the solution is ,

Hence, Option B is the correct 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.
