-------------------------------------------------------------------------------- With its abundance of noun inflections, Icelandic is one of several Germanic languages that is compact when written but can lengthen considerably when translated into English. a: is compact when written but can lengthen considerably when translated into English b: are compact when they are written, but they can lengthen considerably when they are translated in English. c: is compact when written but can lengthen considerably when being translated into English. d: are compact when written but can lengthen considerably in English translation. e: is compact when it is written but can lengthen considerably when translated in English. I think B is the best answer(A,C, & E are out because they use singular verb), because in D "in English translation" is as if while the translation the language lengthens.

Condition 1 l*w = A If length doubled area will increase by 64. Therefore, (2*l)*w = A +64 2*A = A + 64 since lw = A A = 64 Condition 2 l*w = A If width is halved area will decrease by 32. Therefore, l*(w/2) = A - 32
