6. the garages was cleaned every day

7. he has been given a lot of money

8. two hundred people was arrested by the police

10. the meeting has been cancelled

\(x-y=6\Rightarrow\left(x-y\right)^2=36\)

\(\Rightarrow x^2-2xy+y^2=36\)

\(\Rightarrow x^2+y^2-2.30=36\)

\(\Rightarrow x^2+y^2=96\)

Ta có : \(x^2+2xy+y^2=96+60=156\Rightarrow\left(x+y\right)^2=156\)

\(\Rightarrow x+y=\sqrt{156}=2\sqrt{39}\)

Ta có : \(x^2-y^2=\left(x-y\right)\left(x+y\right)\)
