6 Which expression is equivalent to 2x2 + 7x – 15? F
(2x+3)(x - 5)
(2x + 3)(x + 5)
(2x - 3)(x - 5)
H
None of these

c.

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.
