A, B, C, D and E are 5 consecutive points on a straight line. If BC = 2CD, DE = 4, AB = 5 and AC = 11, what is the length of AE?	Pick one:	A) 21	B) 26	C) 30	D) 18	E) 16
A-----B----C--------18----E   Given: 18E = 4 - (i)   AB = 5 - (ii)   AC = 11 - (iii)   BC = 2C18 - (iv)   From (ii) and (iii), BC = 6   From (iv), C18 = 3   Length of AE = AC + C18 + 18E = 11 + 3 + 4=
