\n" ); document.write( "The three sides of a triangle are given by three consecutive integers. If the perimeter is 12 meters, find the length of each side.
\n" ); document.write( "This is how am trying to solve it not so sure, any help please! thanks. The answer from the book is 3,4,5 and i only get 3,3,3. what am i doing wrong?
\n" ); document.write( "3x+(x)=12 3(x)+3=12
\n" ); document.write( "4x=12 3x=9
\n" ); document.write( "x=3 x=3

$\"n\"$ =length of shorter side
\n" ); document.write( "The lengths of the other two sides must be
\n" ); document.write( " $\"n%2B1\"$ and $\"n%2B2\"$ .
\n" ); document.write( "The perimeter is
\n" ); document.write( " $\"n%2B%28n%2B1%29%2Bn%2B2%29=12\"$
\n" ); document.write( "Re-arranging, we get
\n" ); document.write( " $\"%28n%2Bn%2Bn%29%2B%281%2B2%29=12\"$
\n" ); document.write( " $\"3n%2B3=12\"$ --> $\"3n=12-3\"$ --> $\"3n=9\"$ --> $\"n=9%2F3\"$ --> $\"highlight%28n=3%29\"$
\n" ); document.write( "Then $\"n%2B1=3%2B1\"$ --> $\"highlight%28n%2B1=4%29\"$ and
\n" ); document.write( " $\"n%2B2=3%2B2\"$ --> $\"highlight%28n%2B2=5%29\"$ \n" ); document.write( "
