Question

TU has endpoints at T(5, -1) and U(1,-5). How long is TU?*

Answer 1

`√(32)`

Explanation:

We can first input our numbers into the distance formula to get:

`√((5-1)^2+(-1+5)^2)`

Next we can solve within each parenthesis:

`√((4)^2+(4)^2)`

Next we can solve the squares. The square of 4 is 16 so we can input that into the equation

`√(16+16)`

Now we can add the 2 numbers together:

`√(32)`

And that is our final number as
`√(32)` is not a perfect square.
