It's pretty simple all u have to do is write it like this if it's a single number like 6 would be 0.6 any double didget like 16 would be 0.16
60 000 plus 50 000 gives u the total amount
Your surface area is: S=x^2+4xh=84 square inches and h=2 inches; so you get:
x^2+(4×2)x=84
x^2+8x-84=0 qhich is a quadratic equation. Using the quadratic formula you get two results for x:
x1=-14 and x2=6
choose the second (positive)
