This is the distance formula for cartesian coordinate systems, or your typical xy graph. If given two points to find the distance between, you can assign '1' or '2' to the points, i.e. (1,1) and (2,2) could be: (1,1) is (x1,y1) and (2,2) is (x2,y2). It doesn't matter which point is 1 or 2. If we were to use those example points in this formula, we would have:

$\sqrt{(1-2)^{2}+(1-2)^{2}}$

We can simplify and come up with:

$\sqrt{(-1)^{2}+(-1)^{2}}$

= $\sqrt{2}$

We must remember that square roots can be positive OR negative, HOWEVER, because you are looking for a distance it must be positive $\sqrt{2}$ .

Hope this helped!

three friends jogged last month. Richard jogged 9 miles last month. Jena jogged 2 times as many miles as Richard. Brian jogged 4

ANTONII [103]

Answer:

Jena=18 miles Brian=36 miles

Step-by-step explanation:

well if you add what Richard got and double it (9+9=18 or 9x2=18) you get how much Jena ran. then if u add (9+9+9+9=36 or 9x4=36) you get Brians miles he ran
