Question

Can you please check my answer? distance formula

Answer 1

My answer:

CD: C(3,2) D(7, -2)
d = √{[(3 - 7)^2] + [(2 - -2)^2]}
d = √{[-4^2] + [4^2]}
d = √{16 + 16}
d = √32
d ≈ 5.66

AB: A(-11, 4) B(-8, 8)
d = √{[(-11 - -8)^2] + {(4 - 8)^2]}
d = √{[-3^2] + [-4^2]}
d = √{9 + 16}
d = √25
d = 5

5.66 - 5 = 0.66
CD is about 0.66 longer than AB.
