Cary calculated the surface area of a box in the shape of a rectangular prism. she wrote the equation 148=2(6w+6h+hw) to represent the width and height of the box. she solved for w and got w=74-6h/h+6 which of the following is an equivalent equation?
1.w=148-6h/12+h
2.w=148-12h/12+2h
3.w=136-14h
4.w=136-10h

2.

Step-by-step explanation:

Given: Cary calculated the surface area of a box in the shape of a rectangular prism.

The equation written by Cary to represent the width and height of the box.  :

If we open the bracket on the right side, we get

Hence the equation  is equivalent to the equation written by Cary after solved for w is

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
