Carmen is using the quadratic equation (x + 15)(x) = 100 where x represents the width of a picture frame. which statement about the solutions x = 5 and x = –20 is true? a. the solutions x = 5 and x = –20 are reasonable. b. the solution x = 5 should be kept, but x = –20 is unreasonable. c. the solution x = –20 should be kept, but x = 5 is unreasonable. d. the solutions x = 5 and x = –20 are unreasonable.
