Algebra.Com's Answer #38985 by rcmcc(152)![]() ![]() You can put this solution on YOUR website! you can solve this question by making a simple linear equation. \n" ); document.write( "let the width of the pool be x\r \n" ); document.write( "\n" ); document.write( "since the length is 10 feet longer than the width, it can be stated as; \n" ); document.write( "x+10 \n" ); document.write( "But when calculating X you must also calculate the opposing side, so simply multiply your equation by 2 to calculate in all the sides.\r \n" ); document.write( "\n" ); document.write( "you must form an equation, take the length, and add to the width and multiply both by 2. \n" ); document.write( "so.\r \n" ); document.write( "\n" ); document.write( "2(x+10)+2(x)=68\r \n" ); document.write( "\n" ); document.write( "now you can solve for X, \n" ); document.write( "first you mus expand the brackets \n" ); document.write( "2X+20+2X=68 \n" ); document.write( "now you can combine like terms, and subtract 20 from each side. \n" ); document.write( "4X=48 \n" ); document.write( "you divide out 4 to isolate X \n" ); document.write( "x=12\r \n" ); document.write( "\n" ); document.write( "the width of the pool is 12 feet and the length is 22 feet (12+10) \n" ); document.write( " |
