What is the value of the expression below -0./5) + 0.4 + (-3/4) need answers pls

Step-by-step explanation:

Convert the ftactions to the decimal:

Therefore we have:

We know

(-)(-) → (+)

(-)(+) → (-)

Therefore:

Use the commutative property a + b = b + a

and  the associative property (a + b) + c = a + (b + c)

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.
