HELP ASAP

Answer 1

AB = 5
`√(2)`

Explanation:

Calculate the distance using the distance formula

d =
`\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }`

with (x₁, y₁ ) = A(6, 3) and (x₂, y₂ ) = B(- 1, 4)

AB =
`√((-1-6)^2+(4-3)^2)`

=
`√((-7)^2+1^2)`

=
`√(49+1)`

=
`√(50)`

= 5
`√(2)` ← exact value

≈ 7.07 ( to 2 dec. places )
