Algebra.Com's Answer #650261 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Perimeter is the sum of all three sides. \n" ); document.write( "Let's call the missing side x. Then we can write \n" ); document.write( "x + 5m-7 + 2m+5 = 24m-6 \n" ); document.write( "x + 7m-2 = 24m-6 \n" ); document.write( "Now subtract 7m and add 2...we get \n" ); document.write( "x - 2 = 17m-6 \n" ); document.write( "x = 17m-4 \n" ); document.write( "the third side... \n" ); document.write( " |
