    excellent :) so, |dw:1436373071855:dw| now we know, E ( 12 ) = 24 E ( 8 ) = 16 E ( 4 ) = 8 E ( 6 ) = 12 If we look at option A. " E ( 8 ) + E ( 4 )" . What would this equal to?

    perfect :)! So we know option A and option D are correct. Now are option B and C correct?

    Option B is E (6)+ 6 so wouldn't that be E (12)?

    Option C isn't correct because it's not 24 or 12 so that can't be right, right?

    well, we know E (12) = 24 right? :D We also know E ( 6 ) = 12 option B " E ( 6 ) + 6" = 12 + 6 = 18 :O So B would not be correct. And true :) option C isn't correct either!
