Question

I NEED help.
i do not understand this question at all

Answer 1

1)8.5 units

2)7 units

Explanation:

To find the distance between two points use distance formula.

1) ( 3 , 1) & (6 , 9)

`\sf \boxed{\bf Distance = √((x_1-x_2)^2+(y_1-y_2)^2)}`

`\sf AB = √((3-6)^2+(1-9)^2)\\\\~~~~~ = √((-3)^2+(-8)^2)\\\\~~~~~ =√(9+64)\\\\~~~~~=√(73)\\\\`

= 8.5

_________________________________________________

2)(3 , 8) & (8 , 3)

`\sf AB = √((3-8)^2+(8-3)^2)\\\\`

`\sf =√((-5)^2+(5)^2)\\\\=√(25+25)\\\\=√(50)\\\\=7`
