Re-write the quadratic function below in Standard Form
y = -(x + 8)(x + 7)

y = - x² - 15x - 56

Step-by-step explanation:

y = - (x + 8)(x + 7) ← expand factors using FOIL

  = - (x² + 15x + 56) ← distribute parenthesis by - 1

y = - x² - 15x - 56 ← in standard form

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.
