Answer:

Step-by-step explanation:

your equation is k - 12 = -8, this is because you are taking 12 away from k and that would equal -8.

add 12 to both sides to isolate the variable: k = 4

you get k = 4

max2010maxim [7]

(Refer to picture for diagram.)

Area of base $=w^{2}$
Area of one side $=\frac{8}{w^{2}}*w=\frac{8}{w}$

Cost of base material $=8w^{2}$
Cost of material for a side $=6*\frac{8}{w}=\frac{48}{w}$
There are 4 sides so $4*\frac{48}{w}=\frac{192}{w}$

Total cost $C(w)=8w^{2}+\frac{192}{w}$
