Asubmarine is underwater. its position is 645 feet below sea level. it rises in the water 100 feet and then descends 100 feet. what integer represents the change in the? submarine's position in the? water?

The answer would be 0

because the water raised up at 100 and then falls down at 100

so 100 + -100 = 0

You just have to read the word problem a couple times then you will see the answer. Like when it says rising you know that's a postive number and when it says descends it means to go downwards so a negative number.

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
