Answer 2

(2-5,3-8)

(-3,-5)?
sqrt(-3^2)+(-5^2?)

Answer 4

@freckles

Answer 5

checking the result myself
\[\sqrt{(2-5)^2+(3-8)^2} \\ \sqrt{(-3)^2+(-5)^2} \\ \sqrt{3^2+5^2}\]
so far you are right except put the square round the (-3) and (-5)
like (-3)^2 and not (-3^2)

Answer 6

so sqrt of 34?

Answer 7

Yeh i saw what happens when I do it the way I did it comes up imaginary
