Asked by Robert

George calculated the distance between (2, 4) and (6, 3) using the distance formula. His work is shown below.
1. d = StartRoot (6 minus 2) squared + (3 minus 4) squared EndRoot. 2. d = StartRoot (4) squared + (negative 1) squared EndRoot. 3. d = StartRoot 16 + 1 EndRoot. 4. d = StartRoot 17 EndRoot
Analyze George’s work. Is he correct? If not, what was his mistake?
Yes, he is correct.
No, he substituted values in the wrong places.
No, he didn’t use the proper order of operations.
No, he evaluated the powers incorrectly.

Yes, he is correct.

His substitution and arithmetic are all correct: (6−2) = 4, (3−4) = −1, and 4^2 = 16, (−1)^2 = 1, so the distance is sqrt(16+1) = sqrt(17).
