So hmm notice the picture below
thus, the perimeter of the gutter is just w + w + l, or 2w +l
thus
take the derivative of A(w), zero it out, check any critical points in the interval of (0, 22), for a maxima
recall, the aluminum sheet is just 22inches long, thus, whatever the "depth" or "w" is, has to be more than 0, and less than 22

i hope this picture help u
Answer:
See explanation
Step-by-step explanation:
It is impossible to take the square root of a negative number. Try any value, <em>nothing works</em>. , and
. It just doesn't work. This is why there is no real number that satisfies
(however it is represented as
, i being "the imaginary number" that mathematicians made up to represent it).
When we are finding the cube root of a number, we are looking for a number that when multiplied by itself 3 times, will equal the number.
This is different than squared. Any number, positive or negative, squared will be positive. However, we can test out values and see we can end up with a negative when cubing.
For example:
HOWEVER:
We know that , this means that
(as
)
