$\"%28r+%2B+4%29%5E2+=+r%5E2+%2B+8%5E2\"$ is the correct setup.
\n" ); document.write( "When you do the algebra on this, I wouldn't worry about the $\"r%5E2\"$ canceling out. \r
\n" ); document.write( "\n" ); document.write( "Here is how I would work this.
\n" ); document.write( " $\"%28r+%2B+4%29%5E2+=+r%5E2+%2B+64\"$
\n" ); document.write( " $\"r%5E2+%2B+8r+%2B+16+=+r%5E2+%2B+64\"$ Then clean this up a bit. Cancel the $\"r%5E2\"$ and subtract the 16 on both sides.
\n" ); document.write( " $\"8r+=+48\"$ Then divide both sides by 8 and you're done.
\n" ); document.write( " $\"r+=+6\"$
\n" ); document.write( "So, the sides for the triangle are 6, 8, and 10. If you cut each in half, this is a special type of right triangle called a 3,4,5 triangle. \n" ); document.write( "
