Question

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:1. $p = 4l + 4w + 4h$2. $\frac{p}{4} = \frac{4l+4w+4h}{4}$3. $\frac{p}{4} = l + w + h$4. $h = \frac{p}{4} -$which expression should follow the subtraction in hallies equation?$\bigcirc (l + w)$$\bigcirc (l - w)$$\bigcirc (\frac{l+w}{4})$$\bigcirc (\frac{l-w}{4})$

Explanation:

Step1: Isolate h term

Starting from $\frac{p}{4} = l + w + h$

Step2: Rearrange to solve for h

Subtract $l + w$ from both sides:
$h = \frac{p}{4} - (l + w)$

Answer:

$\boldsymbol{(l + w)}$
