Question

Plz help me on question 30 plz

Answer 1

5

Explanation:

D=
`√((8-4)^2+(1-4)^2)`

D=
`√(4^2+(-3)^2)`

D=
`√(16+9)`

D=
`√(25\\)`

D=5

Answer 2

Answer: B

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)}`

`= √(16+9)`

`= √(25)`

`= 5`
