Question

this is the second question I don't undrstand​

Answer 1

Answer:

$d=\sqrt{58}$

Step-by-step explanation:

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

Simply plug in your coordinates into the distance formula to find the length of AB:

$d=\sqrt{(9-2)^2+(4-1)^2}$

$d=\sqrt{(7)^2+(3)^2}$

$d=\sqrt{49+9}$

$d=\sqrt{58}$

Answer 2

D= __
/58
