Which of the following is an example of the distributive property?

a. 3(10 + 5) = 3(5 + 10)
b. 3(10 + 5) = (10 + 5)3
c. 3(10 + 5) = 30 + 15
d. 3(10 + 5) = 3(15)

i need some , i really don't remember this lesson, though i do think it is either a or b.

i did try to do the math myself and rounded it up to those two, but in the end they're both 15. though a would be what i think it is, seeing as the 3 is in front, not in the back.

in advance.

Well multiply the three by the first number. You get 30. Then multiply it by the second number and you get 15.

The answer is C 3(10+5)=30+15

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.
