Question

which expression gives the distance between the points (2,5)and (-4,8)​

Answer 1

Answer:

$3\sqrt{5}$

Step-by-step explanation:

Use the distance formula:

$\sqrt{(8-5)^2+(-4-2)^2}=\sqrt{9+36}=3\sqrt{5}$

Answer 2

Answer: $\sqrt{45} =3\sqrt{5}$

Step-by-step explanation:

To find the distance between 2 points use this formula:

$\sqrt{(x1-x2) ^{2} +(y1-y2)^{2} }$

rad[(2+4)^2+(5-8)^2)]

=rad[36+9]

=rad45

=3rad5
