Regular polygon area = n*side^2 / (4 * tan (180/n))
where "n" is number of sides
The formula is dependent on the side^2 term,
So, if we have an octagon that has sides 4 times as large, that means the area will be sixteen times larger.
side^2 = 4^2 = 16
So we multiply 25 cm^2 by 16 and we get
400 square centimeters.

The answer to the problem is x=8
The general or standard form of a parabola is
(y-k) = a(x+h)^2
h,k are the intersection points of parabola
Intersection points are where y= 0, or x=0
itsnorigin at (,0,0)that means h=0, k=0
it passes through points (-1,2) and (1,2)
So then
y= ax^2 , 2 = a (-1)^2
this means a= 2
Then results standard form equation
Y = 2• X^2
350-215=134, 134/11=12.27, 12.27*20 =245.4, 350-245.4=104.6
104.6 degress F
