You can put this solution on YOUR website!
You could draw and label a triangle, one side is 8, other sides are x and y. and since x/y is 2/3, you can also make the equations:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Perimeter given as 18, so $\"8%2Bx%2By=18\"$ ,
\n" ); document.write( "and since ratio of the two other sides to each other, x/y=2/3, gives you $\"+x=2y%2F3\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute that last formula for x into the perimeter equation, and solve for y; then calculate for x. You could choose other ways to solve for x and y, but that one may be simplest.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If done as I suggested, find $\"y=10%2A%283%2F5%29=6\"$ . y=6.
\n" ); document.write( " $\"x=2%2A%286%29%2F3\"$ =...?... \n" ); document.write( "

\n" );
