\bf \sqrt{2}\left(3\sqrt{2}+\sqrt{18}  \right)~~
\begin{cases}
18=2\cdot 3\cdot 3\\
\qquad 2\cdot 3^2
\end{cases}\implies \sqrt{2}\left(3\sqrt{2}+\sqrt{2\cdot 3^2}  \right)
\\\\\\
\sqrt{2}\left(3\sqrt{2}+3\sqrt{2}  \right)\implies \sqrt{2}\left(6\sqrt{2} \right)\implies 6\left(\sqrt{2}\right)^2\implies 6\cdot 2\implies \stackrel{rational}{12}

Grace [21]

Answer: 20

Step-by-step explanation:

x+y=5

x-y=4

---------

x+y=5

x=4+y

--------

(4+y)+y=5

4+y+y=5

 4+2y=5

      2y=1

        y=0.5

        x=4.5

---------

x²-y²=(4.5)²-(0.5)²=20.25-0.25=20

13+x+195=13(x+15)...
LUCKY_DIMON [66]
First, let's expand the right side.  Now our equation is

13+x+195=13x+195

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right.  We get:

-12x=-13

And then we can make this

12x=13

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
