Algebra.Com's Answer #93805 by ilana(307)![]() ![]() ![]() You can put this solution on YOUR website! If M is the midpoint of CD, how is the length of CM related to the length of CD? CM is half the length of CD (MD is the other half of the segment). So 2*3x=8x-14, 6x=8x-14, 14=2x, 7=x. \n" ); document.write( "So CM is 21 and CD is 42. \n" ); document.write( " |
