Answer 1

IT IS NOT POSSIBLE TO ANSWER THIS QUESTION

Explanation:

Answer 2

`√(89)`

Explanation:

Calculate the distance d using the distance formula

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

with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (4, 7)

d =
`√((4+1)^2+(7+1)^2)`

=
`√(5^2+8^2)`

=
`√(25+64)`

=
`√(89)`
