Answer:

IT IS NOT POSSIBLE TO ANSWER THIS QUESTION

Step-by-step explanation:

Answer 2

Answer:

$\sqrt{89}$

Step-by-step 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 = $\sqrt{(4+1)^2+(7+1)^2}$

   = $\sqrt{5^2+8^2}$

   = $\sqrt{25+64}$

   = $\sqrt{89}$
