Jenny has 10 batteries. she needs more for a school project. batteries are sold in packages of 4.if jenny buys 16 packages of batteries, how many batteries will jenny now have for the school project?

74

Step-by-step explanation:

Multiply 16 (packs of batteries) by 4 (amount in each package) to get 64,

⇒ 6 * 4 = 24; 10 * 4 = 40; 24 + 40 = 64

then add 10 (batteries she had before buying more).

64 + 10 = 74.

Now Jenny has 74 batteries for her school project.

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.
