Answer: Choice D</h3><h3>
sin^2(x) + 1</h3>
========================================================
Work Shown:
2sin^2(x) + cos^2(x)
2sin^2(x) + 1 - sin^2(x) .. see note below
[ 2sin^2(x) - sin^2(x) ] + 1
sin^2(x) + 1
note for step 2 above, I used the Pythagorean trig identity (or a slight variation of it) to replace cos^2(x) with 1-sin^2(x).
Start by laying out the 12.
The neighbors of 12 must be 11 and 10.
The neighbor of 11 must be 9, and the neighbor of 10 must be 8, and so on and so forth, until you get a unique arrangement.
