2 numbers that add up to 6 but also when multiplied -7 is the outcome

Let the numbers be x and y

According to the data : xy=-15 and x+y=-7

xy=-15

x+y=-7

y=-7-x

x(-x-7)=-15

y=-7-x

-x^2-7x=-15

y=-7-x

x^2+7x-15=0

y=-7-x

x=(-7±sqrt(7*7+4*15))/2

y=-7-x

x=(-7±sqrt(109))/2

Goes to two systems.

1)  

y=-7-x

x=(-7+sqrt(109))/2

y=-7+3.5-sqrt(109))/2

x=(-7+sqrt(109))/2

y=-3.5-sqrt(109))/2

x=(-7+sqrt(109))/2

2)

y=-7-x

x=(-7-sqrt(109))/2

y=-7+3.5+sqrt(109))/2

x=(-7-sqrt(109))/2

y=-3.5+sqrt(109))/2

x=(-7-sqrt(109))/2

Step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
