If a and c are real numbers such that 0<a<c, which of the following must be true?

A) -a<-c

B) 2a sqrt c

D) a^2 > c^2

2) a/c > 1

Wait–what happened to the answer choices? A, B, D, 2?

Sorry I didn’t notice when I submitted it..

A) -a < -c

B) 2a sqrt c

D) a^2 > c^2

E) a/c > 1

B must be true–if you multiply both sides of the original inequality by 2, that’s what you get. Other choices MIGHT be true for some values of a and c, but will also be false for other values of a and c.
