Find the answer to
(x + y + 2)( y + 1)

Step-by-step explanation:

The given expression:

Using left distributive property:

, where a, b, c are any arbitrary expressions.

Using right distributive property:

, where a, b, c are any arbitrary expressions.

Hence,

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.
