Factor the quadratic expression. 2x^2-8x-10

I don’t know the answer I just need some points to ask more questions

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.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
