Recall that the volume of a regular prism is given by the area of the base times the height.
Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.
Recall that the are of a triangle is given by 1/2 base times height.
Thus the area of of the pentagon base of the prism is given by

Therefore, the volume of the prism is given by
5x-3x^2/2x^4 =x(5-3x) / 2x.(x^3), simplified by x, we have <span>5-3x/2x^3, (x≠0)
</span>so the answer is <span>C.5-3x/2x^3, (x≠0)</span>
The simplified answer to that radical is attached
Answer:I believe y would also be 0
Step-by-step explanation: so sorry if I’m wrong but good luck! :)
Answer:
x = 11
Step-by-step explanation:
9x + 1 + 100 = 180
9x + 101 = 180
9x = 99
x = 11
