Algebra.Com's Answer #420218 by jpvn2015(54)![]() ![]() ![]() You can put this solution on YOUR website! The answer is C, 28. Here is how I got it: \r \n" ); document.write( "\n" ); document.write( "If LN = 40, then 40 must equal LM+ MN or 4x-12+x+2. \n" ); document.write( "In other words, 40 = 4x-12+x+2 \n" ); document.write( "Combine and add like terms: 40=5x-10 \n" ); document.write( "Add ten to both sides: 50 = 5x \n" ); document.write( "Dividing both sides by 5 yields: x=10 \r \n" ); document.write( "\n" ); document.write( "So, once we find x (10), we can substitute it in for LM (or ML). \n" ); document.write( "4x - 12 \n" ); document.write( "4(10) - 12 \n" ); document.write( "40-12 \n" ); document.write( "28. \r \n" ); document.write( "\n" ); document.write( "Thus, C is the correct answer. \n" ); document.write( " |
