Answer:
[tex] \sqrt{45} = 6.7[/tex]
Step-by-step explanation:
[tex] \sqrt{(7 - 1) {}^{2} + (1( - 2)) {}^{2} } [/tex]
that is how you weould set it up.
[tex] \sqrt{(6) {}^{2} + (3) {}^{2} } [/tex]
thats what you'd do if you added or subtracted what was in the perenthesis
[tex]36 + 9 = 45[/tex]
rember that you have to put it back into square root
[tex] \sqrt{45 } = 6.7[/tex]
and that would be your final answer!
