Answer:
-16n-41
Step-by-step explanation:
The number (another number) represent multiplication between the 2 numbers, so if you have this problem :
4 (1,000,000) , it is 4 x 1,000,000, which is 4,000,000
and if you have :
7 (100) , it is also 7 x 100 which is 700
and if you have :
2 (1) , it is also 2 x 1 which is 2
now, there is (+) between each number, but the most important rule is multiplication ALWAYS comes first and not by the places, but by solving, so you ALWAYS solve multiplication first and then you add them, if you add : you will get :
4,000,000 + 700 + 2 = 4,000,702

Here L = W, but H can be different.
The sum L+H+W must be less than or equal to 192 cm.
We can solve L + H + W = 192 for H: H = 192 - W - L. Remembering that W = L, the formula for H becomes 192 - 2W.
The formula for volume would be V = L*W*H.
This becomes V = W*W*H, or V = W^2*(192-2W)
Multiplying this out: V = w^2*192 - 2W^3
Two ways of determining W:
1) graph V = 192W^2 - 2W^3 and determine the value of W at which V is at a max with the constraint W + L + H is equal to or smaller than 192.
2) Differentiate V with respect to W and set the result equal to zero:
384W - 6W^2 = 0. Solving for W: W(384 - 6W) = 0.
W = 0 is trivial, so just solve 384 - 6W = 0 for W: 6W = 384, and W = 64.
The width is 64 cm, the length is 64 cm also, and the height is (192-2W) cm, or 64 cm.
These dimensions produce the max volume.
