Answer:
see explanation
Step-by-step explanation:
2B + 3C
= 2
+ 3 ![\left[\begin{array}{ccc}1&-1\\-6&3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%26-1%5C%5C-6%263%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiply each element in the matrices by the scalar quantity, that is
=
+ ![\left[\begin{array}{ccc}3&-3\\-18&9\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-3%5C%5C-18%269%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Add corresponding elements from each matrix
= ![\left[\begin{array}{ccc}8+3&-10-3\\-4-18&2+9\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D8%2B3%26-10-3%5C%5C-4-18%262%2B9%5C%5C%5Cend%7Barray%7D%5Cright%5D)
= ![\left[\begin{array}{ccc}11&-13\\-22&11\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D11%26-13%5C%5C-22%2611%5C%5C%5Cend%7Barray%7D%5Cright%5D)
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
