Answer 1

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

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

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

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

$\sqrt{ 4 + 16}$

$\sqrt{20}$
