Answer: 1.6 N/cm^2
Step-by-step explanation:
Answer:
1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies
2) Now let's consider any real number a no matter positive or negative we will have that:
Or in the other case:
So then we can conclude that the expression is a general rule and is true
Step-by-step explanation:
For this case we can verify if the following expression is true or false:
The sum of x and it’s opposite is always zero?
If we want to proof this we need to show that for any number is true.

Answer:
sometimes
Step-by-step explanation:
If the polygon is regular that is the length of each side of the polygon is equal and each angle is equal in that case only interior angles are equal .
For a polygon even if a side length is different or interior angle is different then its a irregular polygon and then in that case each interior angle cannot be termed as equal.
Thus, we know that that there are two type of polygon regular and irregular.
Thus, it can be said that it is not necessary that Each of the interior angles in a polygon are equal always
Also it can be said that it is not necessary that Each of the interior angles in a polygon are never equal (as regular polygon have equal angles)
Thus, we can only say that each of the interior angles in a polygon are sometimes equal .
5.7 is the answer because if one side is 7.9 the parallel is the same a rectangle. The is you add those, you get 15.8. The equation now is 15.8+x=27.2. 27.2-15.8 is 11.4 which is then divided to find the two sides which makes them 5.7.
The absolute value of 1 1/4 is -1 1/4
the absolute value of -11/6 is 11/6
