Need with question number 11. can’t figure it out.

A. 5/18 x 13/2

Step-by-step explanation:

To convert a mixed number to a fraction, multiply the whole number by the denominator, then add that to the numerator.

3x5=15, add 3 and you get 18.

6x2=12, add 1 and you get 13.

18/2 divided by 13/2 is not an option, so if you flip which number is on top for the first fraction an multiply, it would be the same as if you were to divide it.

step-by-step explanation:

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.
