I believe the 2 ways would be

and

and this equation is significant because it is the perimeter formula
Answer:
The answer is B
I had search that up before
Answer:
c
Step-by-step explanation:
Sounds like your describing complementary angles (a pair of angles that add up to be 90 degrees) but not super sure based on that description you have there.
Tell me does it look like this:
Answer:
(a) The range of the function represents the set of values on the y-axis. We see that function has an absolute maximum, then the range of the function is:
![Ran\{f(x)\} = (-\infty, 4]](https://tex.z-dn.net/?f=Ran%5C%7Bf%28x%29%5C%7D%20%3D%20%28-%5Cinfty%2C%204%5D)
(b) The location of the maximum is represented by its ordered pair. After direct observation, we located this maximum at 
(c) By direct observation we find that the value of
when
is -12.
(d) By direct observation we conclude that the values of
when
are -4.8 and 2.
