2 × n - 1 = x
Step-by-step explanation:
for example:
![2(4) - 1 = 7](https://tex.z-dn.net/?f=2%284%29%20-%201%20%3D%207)
![2(5) - 1 = x \\ 10 - 1 = x \\ x = 9](https://tex.z-dn.net/?f=2%285%29%20-%201%20%3D%20x%20%5C%5C%2010%20-%201%20%3D%20x%20%5C%5C%20x%20%3D%209)
Answer:
Step-by-step explanation:
-8×+40>-16
For a regular n-agon with side length "s" and apothem "h", the area will be
.. A = n*(1/2)*s*h
Your area is
.. A = 10*(1/2)*(3.25 m)*(5 m) ≈ 81.3 m^2
