Did I do this problem correctly?
Find the distance between the given points: (5, 5) and (0, 12).
D=sqrt[(12+5)^2+(0+5)^2]
D= sqrt[289+25]
D=314
D~17.720
Is this correct?
Thanks.

not correct
in
D=sqrt[(12+5)^2+(0+5)^2]
you subtracted the x's correctly, but you added the y's
should have been
D=sqrt[(125)^2+(0+5)^2]
take it from there

So then it should look like this:
D= sqrt[(125)^2+(0+5)^2
D= sqrt [49+25]
D=sqrt 74
d~8.602
Is this correct?
