You need to have a password with 6 letters followed by 3 odd digits between 0 and 9 , inclusive. If the characters and digits cannot be used more than once, how many choices do you have for your password?

Step-by-step explanation:

(26!/20!)(5!/2!)=9945936000

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.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
