These are the real solutions to the equation.
The fraction of the image in blue with respect to the <em>entire</em> hexagon is .
Initially we proceed to create auxiliar constructions , represented by red line segments, to re-define the hexagon as a sum of standard figures. According to the figure, we find two types of triangles (type-1 and type-2), and the following relationship between the two types:
(1)
Where:
- Area of a type-1 triangle.
- Area of a type-2 triangle.
The formulae for the area of the shaded region () and the <em>entire</em> hexagon (
) are, respectively:
(2)
(3)
And the fraction of the image in blue is:

Answer:
its the last one.
Step-by-step explanation:
easy way to do inverse functions:
write out equation :
y = 2 + 2
Switch the x and y:
x = 2 + 2
Solve for y :
x = 2 + 2
subtract 2 both sides
x - 2 = 2
Divide both sides by 2
-
=
reduce fraction and square root both sides
