Algebra.Com's Answer #330235 by cleomenius(959)![]() ![]() You can put this solution on YOUR website! (3x + 2)(x + 2) = 3x^2 + 208 \n" ); document.write( "3x^2 + 8x + 4 = 3x^2 + 208 We can subtrate 3x^2 and 4 from both sides. \n" ); document.write( "8x = 204 \n" ); document.write( "x = 25.5m width, 76.5m length. \n" ); document.write( "(25.5)(76.5) = 1950.75 m^2 \n" ); document.write( "(27.5)(78.5) = 2158.75 m^2 \n" ); document.write( "The difference is 208m^2, this is a check. \n" ); document.write( "Cleomenius.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
