Hello, daleross9!

The distance between the points (-8, 2) and (8, 4) is __.

I am confused. I am getting 2 answers, which one is it?\(\displaystyle \;\;\) . . . neither!

4(171/2) and 2(341/2) \(\displaystyle \;\) What are these?
On this planet, the Distance Formula goes like this:

Given two point \(\displaystyle P(x_1,\,y_1)\) and \(\displaystyle Q(x_2,\,y_2)\)

\(\displaystyle \;\;\)the distance \(\displaystyle \overline{PQ}\) is given by: \(\displaystyle \:\sqrt{\left(x_2\,-\,x_1\right)^2\,+\,\left(y_2\,-\,y_1\right)^2}\)


~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

And "I got 6(21/2)" still doesn't make sense.

If that's the answer (the distance), why didn't you multiply them?
\(\displaystyle \;\;\;6\,\times\,\frac{21}{2}\:=\:63\)

If it means something else, it's like no symbols we've ever heard of.
 
The distance between the points (-8, 2) and (8, 4) is

a. 6(21/2)
b. 2(341/2)
c. 4(171/2)
d. 2(651/2)
e. none of these

Yes, we saw what the exercise was. Did you see the replies?

You have been given the formula to use; plug in your numbers and find the answer. If you're not sure of your answer, please reply showing all of your steps.

Thank you.

Soroban already gave you a complete solution, daleross9. Did you even look? :roll:
