Answer:

the number that goes beneath the radical symbol is 20

Step-by-step explanation:

distance formula:

\sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2}   }

use the two coordinates given in the graph

i) (-3,3)

x1 = -3

y1 = 3

ii) (-1,-1)

x2 = -1

y2 = -1

substitute the values into the formula

\sqrt{( - 1 - ( - 3)) {}^{2} + ( - 1 - 3) {}^{2}  }

\sqrt{( - 1 + 3) {}^{2} + ( - 1 - 3) {}^{2}  }

\sqrt{   {2}^{2}  + ( - 4) {}^{2} }

\sqrt{ 4  + 16}

\sqrt{20}
