Algebra.Com's Answer #220860 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, \n" ); document.write( "Let's have x represent the shortest side. The other side will be x+7 and the other is shown by 2x+3. Now we can set up the equation as: \n" ); document.write( "x+(x+7)+(2x+3)=30 Combine like terms and subtract 10 from both sides to get: \n" ); document.write( "4x=20 Divide both sides by 4 to get: \n" ); document.write( "x=5 \n" ); document.write( "So the short side is 5 cm. I'll let you figure out the other sides now. \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
