Question

Unit Test Review

Answer 1

Answer:

25

Step-by-step explanation:

You would use the distance formula.

d=

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

plug in your numbers to get

$\sqrt{( - 13 - 11) {}^{2} + (9 - 2) {}^{2} }$

simplify down to get

$\sqrt{( - 24) {}^{2} + (7) {}^{2} }$

solve the squared to get

$\sqrt{576 + 49}$

add to get

$\sqrt{625}$

which equals

25

because 25 is the square root of 625

(25×25=625)
