Algebra.Com's Answer #512 by usyim88hk(158)![]() ![]() ![]() You can put this solution on YOUR website! Let x be the length of the first side: \n" ); document.write( "x = first side \n" ); document.write( "x+10 = second side \n" ); document.write( "2x+6 = third side \n" ); document.write( "Now set up an equation: \n" ); document.write( "x+x+10+2x+6 = 60 (because three sides add up to 60) \n" ); document.write( "4x + 16 = 60 \n" ); document.write( "4x = 44 \n" ); document.write( "x = 11 \n" ); document.write( "So the length of the first side is 11 \n" ); document.write( "the length of the second side is 21 \n" ); document.write( "the length of the third side is 28 \n" ); document.write( " |
