I need help... This is something that is hard to admit but I am in 6th grade and I do not know how to do the distributive property... Can someone please help me? You can laugh if you want because I know that is is sad. So feel free to laugh

Step-by-step explanation:

1/2(10x+20y+10z)=?

5x + 10y + 5z

Just multiply the outer number "1/2" into the parenthesis.

1/2 * 10x = 5x

1/2 * 20y = 10y

1/2 * 10z = 5z

Then just place it in the same form:

5x + 10y + 5z

So, 1/2(10x+20y+10z) = 5x + 10y + 5z

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.
