Answer:
5x^4 -7x^3-5x^2+5x+1
Step-by-step explanation:
Hey!
You would just add all the numbers up, and by making sure that you combine all like terms. In this case it is just 1-0 = 1 and so the solution would be the same as your question but with a 1 and you would get rid of the -0.
Hope this helps!

Explanation:
Factorizing your equation we get
cot
(
x
)
=
0
 so 
cos
(
x
)
=
0
we get the following Solutions in the given interval
x
=
π
72
 or 
x
=
3
π
2
for the second case we get
cot
(
x
)
=
−
1
 so 
cos
(
x
)
=
−
sin
(
x
)
and we get
x
=
3
π
4
 or 
x
=
7
π

Hint:
To get the Solutions of the last equation you can use
√
sin
(
x
+
π
4
)
=
0

Answer:
The expression is (-24) / 6 = -4degrees which means that in each week the average change in temperature was -4 degrees Celsius.
Step-by-step explanation:
Change in a quantities can as well be interpreted as rate of change which is used in many everyday problems, such as weather forecast, traveling , in science and so on.When we are talking about rate of change it's is usually in ratio such as Miles per hour or feet per second can be used in calculation involving rates of speed. It is how one quality is changing with respect to time , for instance, rate equals distance divided by time: r = d/t. 
 In finance rate of change is also applicable we can have Unit price which is a particular rate that compares a price to some unit of measure. Example is $64 per dozen.
Therefore, Given from the question, 
The temperature of a city changed -24 degrees Celsius ,
Time =6 weeks period. 
Then change is r = d/t. 
= (-24) / 6
Change = (-24) / 6 = -4 degrees
This means that each week the average change in temperature was -4 degrees Celsius.
