The two numbers that multiply to get 35 and add to 2 are 7 and -5. When you multiply them (7 * -5), you get -35, and when you add them (7 + -5), you get 2. Thus, the numbers are 7 and -5.
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.

To find two numbers that multiply to -100 and add up to -25, we can set up a system of equations. Let's call the two numbers x and y. We have the equations xy = -100 and x + y = -25. By solving these equations simultaneously, we can find that the two numbers are -20 and 5.
Multiply the number by 100 and add a percentage sign.
