Alexxandr [17]

9.      1/3+(x+20)+(x-10)+40=360           10.   1/2x+1/2x+(x-15)+(x-25)+100=540

          1/3+2x+50=360                                  4x+60=540

          (3/1) 1/3+2x=300(3/1)                           4x/4=480/4

          2x=300                                                X=120

6-√8 divide √2-1
agasfer [191]

Answer:

4\sqrt{2}  +2

Step-by-step explanation:

\frac{6-\sqrt{8}}{\sqrt{2}-1}

=\frac{6-\sqrt{8}}{\sqrt{2}-1} ×\frac{\sqrt{2}+1}{\sqrt{2}+1}

=\frac{(6-\sqrt{8})(\sqrt{2}+1)}{2-1}

=6\sqrt{2} + 6 -\sqrt{8}\sqrt{2} - \sqrt{8}

=6\sqrt{2} + 6 - 4 - \sqrt{8}

=6\sqrt{2} + 2 - \sqrt{8}

=6\sqrt{2} + 2 - 2

=4\sqrt{2}  +2

for \sqrt{8} = 2\sqrt{2} ,

\sqrt{8} = \sqrt{2*2*2}

     = (\sqrt{2})^2 × \sqrt{2}

     =2 ×\sqrt{2}
