Neil goes to the pet shop and selects 2 treats for his dog. He chooses 1, puts it back on the shelf and chooses another. What is the probability Neil selects a bone , replaces it, and picks up a collar? 5 balls, 3 collars, 4 bones.

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.

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
