Aren't there quite a few potential nouns in between that can serve as antecedents (I realize that logically, It refers to vitamin E, but wanted to be sure on the rule he...

Re: To furnish a room in a model home, an interior decorater is

Ron,

I apologize but can you please show me how to reduce the factoral in step a? I just solved this by testing 6 (as you discussed in step b).

gmat prep problem is |x| = y-z?

Is |x|= y-z? 1) x+y=z 2)x<0 So I know the answer to this question is C. I rephrased the statement as: is y-x >0 1) we see that y-z =-x or -(y-z)=x. This of course doesn't tell us whether x is (-) or (+) so this is insufficient 2) gives us no information regarding y-z, so not helpful alone Comb...
