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

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:

p = 4l + 4w + 4h

2. StartFraction p Over 4 EndFraction equals StartFraction 4 l plus 4 w plus 4 h Over 4.

3. StartFraction p Over 4 EndFraction equals l plus w plus h. = l + w + h

h = 4. h equals StartFraction p Over 4 EndFraction minus blank. –

Which expression should follow the subtraction in Hallie’s equation?

(l + w)

(l – w)

left-parenthesis StartFraction l plus w Over 4 right-parenthesis.

left-parenthesis StartFraction l plus w Over 4 EndFraction right-parenthesis.

The expression (w + h) + p/4 should follow the subtraction if Hallie's equation is

p = 4l + 4w + 4h

p/4 = l + w + h

h = -

Hallie can use the following equation to solve the problem

p = 4l + 4w + 4h

She can proceed to make h the subject of the formula.

p = 4l + 4w + 4h

When we factor out 4 on the right hand side, we get:

p = 4(l + w + h)

We then divide both side by 4, we have

p/4 = l + w + h

Then, subtracting (l + w) from both sides, we get:

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

We can write it as:

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

And that is what Hallie wanted to obtain.
