Answer:

$\sqrt{74}$

Step-by-step explanation:

<u>Distance between two points</u>

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\textsf{let}\:(x_1,y_1)=(2,-6)$

$\textsf{let}\:(x_2,y_2)=(7,1)$

$d=\textsf{length of segment AB}$

Substituting points into the distance formula and solving for d:

$\implies d=\sqrt{(7-2)^2+(1-(-6))^2}$

$\implies d=\sqrt{5^2+7^2}$

$\implies d=\sqrt{25+49}$

$\implies d=\sqrt{74}$

All I got was:
$\frac{1}{8x^2}$
I simplify what you gave me and I got that.
Hope This Helps!!
