What two numbers multiply together to equal 32 and add together to equal 8?
To find two numbers that multiply to 32 and add up to 8, we can set up a system of equations. Let's call the two numbers x and y. From the given conditions, we have xy = 32 and x + y = 8. By solving these equations simultaneously, we can find the two numbers. The solution is 4 and 8, as 4 * 8 = 32 and 4 + 8 = 8.
