Step-by-step explanation:
Answer:
The equation representing the value of <em>n</em> is, 
.
Step-by-step explanation:
The formula to compute the sum of the degrees, S, of the interior angles of a polygon is:
Compute the equation of <em>n</em> as follows:
Thus, the equation representing the value of <em>n</em> is, .
Area = (side length)^2
Here,
64n^36 = s^2. Take the sqrt of both sides, obtaining 8n^18 = s. This is the principal square root. We use this positive quantity because the measure of side length must be positive.
To find if a series is either geometric or arithmetic:
it must satisfy this property:
Arithmetic:
a(n+1) - a(n) = const
Geometric:
a(n+1)/a(n) = const
In your case:
r1 = 7 -4 = 3
r2 = 12 - 7 = 5
r1 != r2 (not arirthmetic)
Geometric check:
r1 = 7/4
r2 = 12/7
r1 != r2 (not Geometric)
so neither.
