Order 7 of the following sentences so that they form a direct proof of the statement: If n is even, then n² + 3n+ 5 is odd. Direct proof of the statement (in order): Since k is an integer, Choose from this list of sentences By the definition of odd, n = 2k + 1 for some integer k. By the definition of even, n = 2k for some integer k. It follows that n² + 3n+ 5 = (2k)² + 3(2k) + 5 = 4k² + 6k+5 = 2(2k² + 3k + 2) + 1 Hence, n² + 3n+ 5 is odd. Let n be odd. Thus, by the definition of odd, . 2(2k² + 3k + 2) + 1 is odd. 2k² + 3k + 2 is even. 2k² + 3k + 2 is an integer. Let n be even.

Write a formal proof for the following biconditional statement.For all integers n, n^3 is even if and only if n is even.[Hint: For one of the two directions of this proof, you might want to consider a proof using the contrapositive.][Reminder: You may use the parity property, which states that each integeris either even or odd, but not both.]
Important requirements for all questions: • All data members must be declared as “private” • No global variable is allowed to be declared and used • Methods within the class and the requested functions cannot have “cin” or “cout” but it should make use of parameters and return value instead. • “cin” and “cout” should be done in main() or any testing functions • Make sure that you clearly show how the C++ class, its methods and all the functions are being called at least twice and print out its return value and its results properly.
Order the following sentences so that they form a direct proof of the statement: If x and y are rational numbers, then 3x + 2y is also a rational number. Choose from this list of sentences Since b, d are integers, bd is an integer. By the definition of rational numbers, x = a/b where a and b are integers and b# 0, and y = c/d where c and d are integers and d 0. Since 3x + 2y can be expressed as a ratio of two integers where the denominator is not zero, 3x + 2y is a rational number. Since a, b, c, d are integers, 3ad + 2bc is an integer. Let x and y be rational numbers. Since b 0 and d # 0, bd # 0. It follows that 3x + 2y = 3a/b + 2c/d = (3ad + 2bc)/(bd) Direct proof of the statement (in order):
