The area of a rectangular parking lot is represented by the expression 25x^4 − 9y^4. The length and width of the rectangular parking lot can be represented by expressions of the form a + b and a − b. Which expression represents the length? options: 25x + 9y 25x^2 + 9y^2 5x + 3y 5x^2 + 3y^2

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
