Help me solve my polynomial is
-6x^5+6x^4+2x^3-0x^2+0x-3

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.

think the answer would beb

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
