For all integers x>1. <x>=2x+(2x-1)+(2x-2)+......2+1. What is the value of <4>*<2>?	Answers:	A) 60	B) 116	C) 360	D) 263	E) 478
Since <x></x>=2x+(2x-1)+(2x-2)+......2+1=1+2+..+(2x-2)+(2x-1)+2x then<x> is basically the sum of all integers from 1 to 2x, inclusive.   Hence &lt;4&gt; is the sum of all integers from 1 to  2*4</x>=
