I guess you need to find what E is, though sadly this isnt enough information to me....
Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form
The standard form of quadratic equation is

When y=0 then the standard equation becomes

Now we compare the given equation
with
and find the value of a, b,c
-x^2 can be written as -1x^2
a= -1 , b=4 and c=-7
The value of c is -7
None of the above its actually number 22
Hope that helped!?

Answer:
The temperature of Savannah's liquid to the nearest degree Fahrenheit is 75.2.
Step-by-step explanation:
The general formula to convert celsius into fahrenheit is
F=(C*9/5)+32
F= 24 *9/5 +32
F= 24*1.8 +32
F= 43.2 +32
F= 75.2
Therefore, The temperature of Savannah's liquid to the nearest degree Fahrenheit is 75.2
