Answer:

Incorrect

Step-by-step explanation:

To calculate the distance (d) use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 5)

d = [tex]\sqrt{(0+5)^2+(-5-0)^2}[/tex]

   = [tex]\sqrt{5^2+(-5)^2}[/tex]

   = [tex]\sqrt{25+25}[/tex] = [tex]\sqrt{50}[/tex] = [tex]\sqrt{25(2)}[/tex] = 5[tex]\sqrt{2}[/tex] ← exact value
