Decide if the following statements are sometimes, always, or never true. If AB---> and AC---> are opposite rays, then they are collinear
If two rays have the same endpoint, then they form a line
If the union of two rays is a line, then the rays are opposite rays
If PQ---> and PR---> are the same ray, then Q and R are the same point

anser is a

step-by-step explanation:

negitive slope

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

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.
