If C(-2, 4) and D(-6, -1), then what is the length of CD? Round to the nearest tenth.

9514 1404 393

  6.4

Step-by-step explanation:

The length is found from the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((-6 -(-2))² +(-1-4)²) = √((-4)² +(-5)²) = √(16 +25) = √41

  d ≈ 6.4

Step-by-step explanation:

hope it helps

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
