You can calculate polygon area with only apothem OR side length.
apothem only
area = apothem^2 * 6 * tan (180/6)
area = 10.4^2 * 6 * 0.57735
area = 108.16 *

area =

<span>
374.677056
</span>

square yards
side length only
area = 6 * 12^2 * / 4*tan(30)
area = 864 / 4 * 0.57735
area = 864 /

If apothem and side length were given with more precision, the answers would be closer.

Answer:
A,C,D,E
Step-by-step explanation:
If you plug in any random number and you graph it for each one of the problems the answer will change
Ok so direct variation is y=xk
invers is y=k/x
it seems to be that x is on top
therefor
y=x times 1/3
y=xk
direct variation
(5.)
13x + 5 = 83
-5 -5
13x =78
/13 /13
x = 6
(9.)
0.7 , 0.9 , 1.6 , 2.3 , 2.5
median = 1.6
