Astadium has a seating capacity of 65,000 spectators. write an inequality to represent this situation.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
