Rachel is a stunt driver, and she's escaping from a building that is about to explode! ddd represents rachel's remaining distance (in meters) as a function of time ttt (in seconds). d=-38t+220d=−38t+220d, equals, minus, 38, t, plus, 220 what is rachel's speed?

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

faster, im not sure why but i know it is faster

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

the answer is:

mean: 6

mad: 2.14
