PLS HELP SHOW ALL YOUR WORKING OUT THANK YOU IN ADVANCE :D

Answer 1

Answer:

$AB =3 \sqrt{5} = 6.708203932...$

Step-by-step explanation:

$A( - 1,6) \:,\: B(5,3)\\ AB = \sqrt{{(x1 - x2)}^{2} + {(y1 - y2)}^{2} } \\ AB = \sqrt{ {( - 1 - 5)}^{2} + {(6 - 3)}^{2} } \\ AB = \sqrt{ {( - 6)}^{2} + {(3)}^{2} } \\ AB = \sqrt{36 + 9} \\ AB = \sqrt{45} = 3 \sqrt{5} = 6.708203932...$

Answer 2

$AB=\sqrt{(5-(-1))^2+(3-6)^2}=\sqrt{36+9}=\sqrt{45}=3\sqrt5\approx6.71$
