Jim and Carla are scuba diving. Jim started out 12 feet below the surface. He descended 20 feet, rose 3 feet, and descended 7 more feet. Then he rested. Carla started out at the surface. She descended 16 feet, rose 3 feet, and descended another 20 feet. Then she rested. Which person rested at a greater depth? Complete the explanation. Jim rested at (select) feet below the surface while Carla rested at feet below the surface.
Therefore (select) rested at a greater depth.

step-by-step explanation:

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

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 : )
