Which statement illustrates the identity property of addition?

7 + 1 = 8

7 · 1 = 7

7 · 0 = 0

7 + 0 = 7

7 + 0 = 7

Step-by-step explanation:

Identity property of addition states that when we get a same number after adding with another number, then this another number is called additive identity,

Also, the additive identity is always zero.

That is,

a + 0 = a

Where a ∈ R

Thus, the correct option which illustrates the identity property of addition is,

7 + 0 = 7

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.
