Well, you know that the sum of those two numbers aren't zero, as they aren't additive inverses of each other. The sum of these numbers will, furthermore, take the sign of the "greater" number without its sign. For example, 2-3 would be negative, since the negative sign of "3" is of the greater number without its sign.
Answer: 
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- By definition, the perimeter of the figure is the sum of the lenght of each side. Then, you must make the addition as following:
Where 
is the perimeter of the figure.
- Add the like terms, then, you obtain the following expression in simplest form:
Hello.
To find the answer you will have to add them then divide by 2.
So if you add 21.85+-4.7 you will get the answer of 17.15.
Then divide by two to get 8.575
The answer is: 8.575 Celsius
Have a nice day

Therefore, 
Answer: 2/x+4x^2
Step-by-step explanation:
Do distrubitive property.
SO mutiply 2/5 to 5/x which is 10/5x or 2/x
then 2/5 times 10x^2
10*2/5=20/5 or 4
Done.
Have a nice day! :)
