Algebra.Com's Answer #585027 by macston(5194) You can put this solution on YOUR website! P=perimeter=26; W=width; L=length=3W+5in \n" ); document.write( "P=2(L+W) \n" ); document.write( "26=2(L+W) Substitute for L \n" ); document.write( "26=2((3W+5in)+W) \n" ); document.write( "26=2(4W+5in) Divide each side by 2 \n" ); document.write( "13=4W+5in Subtract 5in from each side \n" ); document.write( "8in=4W Divide each side by 4 \n" ); document.write( "2in=W ANSWER 1: The width is 2 inches. \n" ); document.write( "L=3W+5=3(2in)+5in=11 in ANSWER 2: The length is 11 inches. \n" ); document.write( "CHECK: \n" ); document.write( "P=2(L+W) \n" ); document.write( "26in=2(11in+2in) \n" ); document.write( "26in=2(13in) \n" ); document.write( "26in=26in \n" ); document.write( " |
