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

  • Math -

    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?

    I need to simply this equation, but I got stuck. h/(4-sqrt(16+h)) = y First, I multiplied (4+sqrt(16+h)/(4+sqrt(16+h) to both sides, and I ended up with h(4+sqrt(16+h)/-h. Is this correct?
