Start with

-2z+10+7z=16z+7

Simplify the left hand side by summing like terms (the one involving z):

5z+10 = 16z+7

Subtract 5z from both sides:

10 = 11z+7

Subtract 7 from both sides

3 = 11z

Divide both sides by 11:

z = \dfrac{3}{11}

A box with a square base and open top must have a volume of 97556 c m 3 cm3 . We wish to find the dimensions of the box that min
Kipish [7]

Answer:

S(x)  =  x²  +  390224/x

Step-by-step explanation:

Volume of the open box  =   V  = 97556 cm³

Material needed:

Let´s call x the side of the square base then  the  area of the base is

A(b) = x²

For the sides of the box, we have 4 sides each one with area of x*h

where h is the height of the box

The volume of the box    V(b) = 97556 = x²*h   then    h  =  97556/x²

S(x,h) = x²  +  4*x*h*

The surface area of the box as function of x is:

S(x)  =  x²  + 4*x*97556/x²

S(x)  =  x²  +  390224/x
