$$\sqrt{52}, \sqrt{28}, 10, \sqrt{20}$$

hartnn · Answer

Distance between points (x1,y1) and (x2,y2) is 
$\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
does this help ??

anonymous · Answer

$$d=\sqrt({{-2_{1}}}-4_{2})^{2}+(2_{1}+-6_{2})_{2}^{?}$$

Is this right?

hartnn · Answer

don't write the subscripts again, 
$d = \sqrt {(-2-4)^2+(2-(-6))^2}$
can you simplify ?

anonymous · Answer

oh ok so when i do the math I get 70 as d. Is that correct?

anonymous · Answer

I feel as if I did something wrong though...

hartnn · Answer

6^2 is 36 
8^2 is 64 
and whats 36 + 64 ?

anonymous · Answer

100

hartnn · Answer

sqrt (100) =.. ?

hartnn · Answer

did you get how it is 100 ?

anonymous · Answer
