If the sum of two numbers is 13 and their product is 42 determine the number​

6, 7

Step-by-step explanation:

x · y = 42

x · (13 - x) = 42

13x - x² = 42

-x² + 13x - 42 = 0

(-1)(-x² + 13x - 42) = 0(-1)

x² - 13x + 42 = 0

(x - 6)(x - 7) = 0

y = 13 - x

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
