Answer:
-45 feet.
Step-by-step explanation:
That would be - 27 - 32 + 14
= -59 + 14
= -45 feet.
400 times ten because when you multiply you get 40,000.
To complete the square:
we take the coefficient ox "x" (which in this problem is -20)
we divide it by 2
square that number
then add it to both sides of the equation
-20 / 2 = -10
-10^2 = 100
then we add 100 to both sides of the equation:
x^2 -20x
x^2 -20x +100 = 100
******************************************************
To get the roots of the equation, we take the square root of both sides:
(x -10) * (x-10) = 10
(x-10) = square root (10)
x-10 =

There are 9 whole numbers in between 20 and 30
If the temperature at 1:00 is x, then Jonestown's temperature at 3:00 is
x-10-8 (since it dropped 10 degrees then 8 more degrees)=x-18
Using x for Cooperville too, we get x-6-2 (since it drops 6 degrees then 2 more degrees) = x-8
Since -8 is greater than -18, Cooperville's temperature is warmer and Jonestown's temperature is lower aka colder<span />
