a certain store is selling package of 10 pencils and 4 pens for back to school the school manager wants to make a larger package in the same ratio if the larger package has 10 pens how many pencils in the larger package

25 pencils

Step-by-step explanation:

Because  2×5  is 10, multiply 5 by 5 to obtain 25.

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.
