Express the area as a trinomial. \n" ); document.write( ": \n" ); document.write( "Given the Perimeter: \n" ); document.write( "2L + 2W = 8x+2 \n" ); document.write( ": \n" ); document.write( "Given the width as (x+2) \n" ); document.write( "2L + 2(x+2) = 8x+2 \n" ); document.write( "Find L \n" ); document.write( "2L + 2x + 4 = 8x+2 \n" ); document.write( "2L = 8x - 2x + 2 - 4 \n" ); document.write( "2L = 6x - 2 \n" ); document.write( "L = 3x - 1; divided equation by 2 \n" ); document.write( ": \n" ); document.write( "Area = L * W \n" ); document.write( "Area = (3x-1)*(x+2) \n" ); document.write( "FOIL \n" ); document.write( "Area = 3x^2 + 6x - x - 2 \n" ); document.write( "Area = 3x^2 + 5x - 2, is the trinomial representing the area \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Did this help, any questions? \n" ); document.write( " \n" ); document.write( " |
