Find the perimeter of triangle xyz with vertices x(3,7), y(-1,-5) & z (6,-4)

To find the distance between 2 points, we start off by subtracting 2 x values. For the first 2 points, we do (3-(-1))=4. Next, we square it - 4^2=16. We then repeat with the y values - 7-(-5)=12 and 12^2=144. We then add the squares to get 16+144=159, and get the square root of that (sqrt(159)). Repeat the process for the other points until you have the distance from the second point to the third point and the third point to the first point, and then add them all up!

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
