Math question: Find a prime number that can be expressed as the sum of the squares of two positive integers, with a positive difference of 15.

To solve this problem, we need to find two positive integers whose squares differ by 15. Let's denote the smaller integer as x and the larger integer as y. From the given information, we can form the equation y^2 - x^2 = 15. Factoring the difference of squares, we get (y + x)(y - x) = 15. Now, we need to list all possible factors of 15, which are (1, 15) and (3, 5). By solving the resulting systems of equations, we find two potential solutions: (8, 7) and (-4, -1). However, since we are looking for positive integers, only (8, 7) is valid. Thus, the sum of the squares of 8 and 7 is 113 + 64 = 177. However, 177 is not a prime number. Continuing the same process, we find that the sum of squares of 15 and 8 is 225 + 64 = 289. Amazingly, 289 is a perfect square (17^2). Therefore, our answer is 289 (17^2), which can be expressed as the sum of squares of two positive integers, with a difference of 15.

Question: If the number 1129 is multiplied by 3 and then divided by 4, what is the result?

To find the result, we can first multiply 1129 by 3, which equals 3387. Then, we divide 3387 by 4, resulting in a quotient of 846.75. Hence, if the number 1129 is multiplied by 3 and then divided by 4, the final result is 846.75.

Math question: What is the sum of the digits in the number 1129?

To find the sum of the digits in 1129, we add the individual digits: 1 + 1 + 2 + 9 = 13.
