How do you simplify the square root of 97? i'm finding the distance from points (-4, 3) and (5, -1) and the distance between them is the square root of 97. but how do i simplify that, if i make it 9 square root of 16, how do i simplify that further? or is that wrong altogether?

Will give brainliest for correct answer 8. use the distance time graph to answer these questions: a. what does the graph tell us about the velocity of the car? b. what is the average velocity of the car? (show work) c. is the velocity reflected in the graph positive or negative?d. is there any point on the graph where the car is not moving? how do we know?
