10 because it's an even number !
List numbers that multiply to make 28 and find their sums. Since negative times a negative is positive, list the negatives. -1, -28 = -29 -2, -14 = -15 -4, -7 = -11 Aha! -4 and -7 multiply to make 28 and add to -11; therefore, -4 and -7 are the two numbers.
4+7=11 7+4=11 11-4=7 11-7=4

A 7-11 manager makes about 52,000 dollars a year. This amount is set by corporate and is pretty even across the board.

This is a joke-- remove the s from "seven" and you get "even".

Consider the prime factorisation of 693: 693 = 3 x 3 x 7 x 11 If a number is a perfect square, then its prime factors must be separable into two identical groups. For 693 to 'become' a perfect square, it must therefore be multiplied by 7 x 11: 693 x 7 x 11 = 3 x 3 x 7 x 7 x 11 x 11 = (3 x 7 x 11)2 However, N = 7 x 11 = 77 is unsatisfactory, 77 being two-digit and odd. To make N three digit and even (as required), we multiply 77 by an even square number: N = 77 x 22 = 308 [77 x 42 = 1232 is too big. Hence the only solution is N = 308.] Putting this back into the problem, we can justify our solution: 693 x 308 = (3 x 3 x 7 x 11) x (7 x 11 x 2 x 2) = (2 x 3 x 7 x 11)2
