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[(12-5)^2+(0+5)^2]

take it from there

So then it should look like this:

D= sqrt[(12-5)^2+(0+5)^2

D= sqrt [49+25]

D=sqrt 74

d~8.602

Is this correct?
