Question

Plz help me on question 30 plz

Answer 1

Answer:

5

Step-by-step explanation:

D=$\sqrt{(8-4)^2+(1-4)^2}$

D=$\sqrt{4^2+(-3)^2}$

D=$\sqrt{16+9}$

D=$\sqrt{25\\}$

D=5

Answer 2

Answer: B

Step-by-step explanation:

Use the distance formula: $d = \sqrt{(x_2 -x_1)^{2}+(y_2-y_1)^{2}}$

$d_{PQ} = \sqrt{(8-4)^{2}+(1-4)^{2}}$

         $= \sqrt{(4)^{2}+(-3)^{2}}$

         $= \sqrt{16+9}$

         $= \sqrt{25}$

         $= 5$
