Does anyone else seem to be missing possible answer choices to questions in the problem sets?
For example, according to the Algebra Guide 1 Chapter 3 Problem Set Solutions, the answer to question # 11 is (D).
Yet, on my Problem Set page, question 11 doesn't have a (D) answer choice. In fact, no answer choices at all are listed. The formula is provided (x^2 - 2x -15 =0), as well as Quantity A and Quantity B, but no (A), (B), (C), (D) answers.
Questions 12 and 13 do not have possible answer choices listed either.
Any explanation to this situation or helpful information would be extremely appreciated.
Thank you!
