Answer:
b = 4.6 ft
h = 2.3 ft
Step-by-step explanation:
The volume of the tank is given by:

Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.
The surface area can be written as:

The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:

The value of h is then:

Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.

Therefore, the answer is 1) y = 2x - 6
Answer:
X=2
If 21+6=27 then subtract what f(x) is (which is 18) from the 27. 27-18=6 then 3x2=6 so therefore your answer is 2. Hope this helps!!
