Express in radical form, the length of the line segment with endpoints 9-1,2) and (-3,-2). PLEASE HELP AND ALL WORK MUST BE SHOWN!

ok...if you post the work your teachers will look it up and find you plagerized it...so posting on here asking for shown work...is a really bad idea lol...another question...if you get to ask one...i get to ask you one...what is radical?

like the thing that looks like a divsion thing. its like radical 16 would be 4 right? and my teacher told me to use this website

HAHAHAHA...IM CRYING!!! sorry...that thing is called a Square root...also known as a radical...my laughing was not ment to be offensive at all so dont take it wrong...that just made my day...anyway...to answer the question i really need to know where the first parithisis starts... "Express in radical form, the length of the line segment with endpoints 9-1,2) and (-3,-2)." where does the parithisis in the 9-1,2) start? please re write it

Oh oops sorry my bad...(-1,2) and (-3,-2) sorry it suposed to be like that... the nine isnt supposed to be there

@SnuggieLad r you okay over there?

OH ok...i just sat here wracking my brain trying to figure out why you needed it in radical form...you need to use the distance formula... \[d \sqrt{(x_{2}-x _{1})+(y _{2}-y _{1})}\] do you know how to put in the numbers?

no

ok...give me a moment i am going to re make that formula

\[d \sqrt{(-3-1)^{2}+(-2-2)^{2}}\] work that out...dont forget pedmas and i sure hope you know how to fix double negatives...

how?

Denote point (-3,-2) as point (x1, y1). Denote point (-1,2) as point (x2,y2). |dw:1363046231370:dw|
