A universal set U consists of 15 elements. If sets A, B, and Care proper subsets of U and n(U) = 15, n(AB) = n(An C) = n(BNC)=7, n( ABC) = 4, and n(A
UBU C) = 13, determine each of the following.
a) n(AUB)
b) n(AUC)
c) n(
AB)

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.

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
