What is the distance between points (9,8) and (-9,3)

18.68

Step-by-step explanation:

√ ((X2-X1)2+(Y2-Y1)2)

d = √(-9-9)2+(3-8)2

d = √((-18)2+(-5)2)

d = √(324+25)

d = √349

i belive those are the ones that are under 90 degreese.

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.
