A standard paper clip is 1 1/4 inches long. If you laid 75 paper
clips end to end, how long would
the line of paper clips be?

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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.
