Question

HELP ASAP !! - hallie can use the equation p=4l+4w+4h to determine the sum of the lengths of the edges of a rectangular prism. she begins to solve the equation for h but runs out of time. her partial work is shown below:

which expression should follow the subtraction in hallie’s equation

Answer 1

l +w

Explanation:

Answer 2

The correct option is A)
`(l+w)`

Explanation:

Consider the provided equation.

Step 1:
`p=4l+4w+4h`

Step 2: Divide both sides by 4.

`(p)/(4)=(4l+4w+4h)/(4)`

Step 3: Simplify

`(p)/(4)=l+w+h`

Step 4: Subtract l+w from both sides.

`h=(p)/(4)-(l+w)`

The missing expression which follow the subtraction in Hallie's equation is
`(l+w)`

Hence, the correct option is A)
`(l+w)`
