I'd say 40, because most accidents take 2 people to happen.
Answer:
The answer is:
morning: 0c
afternoon: -5c
night: 3c
Step-by-step explanation:
Given that night temperature is 3c
and night temperature was 8c higher than the afternoon temperature
so 3c-8c = -5c
afternoon temperature was 5c lower than the morning temperature
so -5c +5c = 0c

Step-by-step explanation:
Given
![(x_1,y_1) = (-8,8)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%28-8%2C8%29)
![(x_2,y_2) = (-3,8)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%28-3%2C8%29)
![Area = 15](https://tex.z-dn.net/?f=Area%20%3D%2015)
Required
Draw the rectangle on a coordinate plane --- (missing from the question)
First, we calculate the distance between the given pairs.
![D = \sqrt{(x_1 - x_2)^2 + (y_1-y_2)^2}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28x_1%20-%20x_2%29%5E2%20%2B%20%28y_1-y_2%29%5E2%7D)
![D = \sqrt{(-8-(-3))^2 + (8-8)^2}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28-8-%28-3%29%29%5E2%20%2B%20%288-8%29%5E2%7D)
![D = \sqrt{25}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B25%7D)
![D = 5](https://tex.z-dn.net/?f=D%20%3D%205)
So, the distance between the given pairs is 5 units... Let this be the length of the rectangle.
Using:
![Area = Length * Width](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Width)
![15 = 5 * Width](https://tex.z-dn.net/?f=15%20%3D%205%20%2A%20Width)
![Width = \frac{15}{5}](https://tex.z-dn.net/?f=Width%20%3D%20%5Cfrac%7B15%7D%7B5%7D)
![Width = 3](https://tex.z-dn.net/?f=Width%20%3D%203)
The width is 3 units.
This implies that the opposite sides of the rectangle are either 3 units down or 3 units up the given pairs.
Assume they are 3 units up.
and ![(x_2,y_2) = (-3,8)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%28-3%2C8%29)
![(x_3,y_3) = (x_1,y_3 + 3) = (-8,8+3) = (-8,11)](https://tex.z-dn.net/?f=%28x_3%2Cy_3%29%20%3D%20%28x_1%2Cy_3%20%2B%203%29%20%3D%20%28-8%2C8%2B3%29%20%3D%20%28-8%2C11%29)
![(x_4,y_4) = (x_2,y_2 + 3) = (-3,8+3) = (-3,11)](https://tex.z-dn.net/?f=%28x_4%2Cy_4%29%20%3D%20%28x_2%2Cy_2%20%2B%203%29%20%3D%20%28-3%2C8%2B3%29%20%3D%20%28-3%2C11%29)
