Will give a brainlest-geometry the length of the base edge of a pyramid with a regular hexagon base is represented as x. the height of the pyramid is 3 times longer than the base edge.

The height of the pyramid can be represented as 3x

The Area of an equilateral triangle with length x is x^2 sqrt3/4units^2

The area of the hexagon base is Six times the area of the equilateral triangle.

The volume of the pyramid is 3/2 x^3 sqrt3 units^3.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

there is no graph so i cant sorry
