Total cost, C = 8x^2 + 12xz
volume, V = (x^2)*z = 10
C = 8x^2 + 12x*10/x^2
= 8x^2 + 120/x
dC/dx = 16x - 120/x^2 = 0
16x = 120/x^2
x^3 = 120/16
x = 1.957 ft
d^2C/dx^2 = 16 +240/x^3 = +ve for x = 1.957
so, C is minimum when
x = 1.957 ft z = 2.61 ft
Length of the base x is 1.957 ft and height of side z is 2.61 ft
keeping in mind that 4 months is not even a year, since there are 12 months in a year, 4 months is then 4/12 years.

Answer:
B
Step-by-step explanation:
I hope I helped you.
Answer:
x+7 oops x+15 ignore the first answer
Step-by-step explanation:
x+11-8/-2
first do -8/-2=4
so it is x+11+4
11+4
x+15 is the answer
