What two numbers multiply to equal 180 but add up to 31?

Answer 1

211

Answer 2

Let's denote the two numbers as x and y. We know that xy = 180 and x + y = 31. To find the two numbers, we can set up a system of equations. One way to solve this system is by substitution or elimination. By substituting y = 31 - x into the first equation, we get x(31 - x) = 180. This simplifies to x^2 - 31x + 180 = 0. Factoring this quadratic equation gives us (x - 20)(x - 9) = 0. Therefore, the two numbers are 20 and 9.
