Algebra.Com's Answer #710717 by jorel1380(3719)![]() ![]() You can put this solution on YOUR website! 1.Let w and w+6 be the width and the length of the picture, respectively. Then, the frame would be w+6 by w+12. So: \n" ); document.write( "(w+6)(w+12)-(w)(w+6)=288 \n" ); document.write( "Solve for w \n" ); document.write( "2. Let n be the amount that both dimensions need to be increased. Then: \n" ); document.write( "(12+w)(8+w)=2(12)(8)=192 \n" ); document.write( "w²+20w+96=192 \n" ); document.write( "w²+20w-96=0 \n" ); document.write( "Solve for w \n" ); document.write( "3.Let n be the first integer. Then, the second would be n+1. So: \n" ); document.write( "n(n+1)=210 \n" ); document.write( "n²+n-210=0 \n" ); document.write( "Solve for n \n" ); document.write( "☺☺☺☺\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
