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.

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
