Step-by-step explanation:

"collinear" means simply that they are all on the same line.

and that solves the problem right away, right ?

because as we know EF (the long distance between the outermost points) is 14 in, and EC (which is s part of the long distance) is 9 in, that means

CF (the rest of the long distance) = EF - EC = 14-9 = 5 in
