1 x 13
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
The two numbers that multiply to get 13 are 1 and 13. Since 13 is a prime number, it cannot be factored into other whole numbers. Therefore, the only pairs that work are 1 and 13, or their negatives, -1 and -13.
The two numbers that multiply to make 40 and add to make -13 are -8 and -5. When you multiply -8 and -5, you get 40, and when you add them together, you get -13.
The two numbers that multiply to -48 and add up to 13 are 16 and -3. When you multiply them, (16 \times -3 = -48), and when you add them, (16 + (-3) = 13).
