Answer:
Answer is associative property
Step-by-step explanation:
Because it is just different grouping
No its actually B if you add them correctly
If its squared its a 90 degree angle
if its any smaller than that it's an acute angle
and if it's wider it's an obtuse angle
First simplify each absolute value expression to get....
|-7.18| = 7.18
|7.15| = 7.15
|-7.21| = 7.21
|-7.09| = 7.09
|6.99| = 6.99
Keep in mind that absolute value results are always positive (assuming the input isn't 0, in which case the result is 0)
The sorted values from smallest (least) to largest (greatest) is this list
6.99, 7.09, 7.15, 7.18, 7.21
So the proper order of the expressions is
|6.99|, |-7.09|, |7.15|, |-7.18|, |-7.21|
