Hello, \n" ); document.write( "Area of a Triangle is equal to (1/2)base*height \n" ); document.write( "so let's plug in what we know: (note: represent base as x) \n" ); document.write( "36=(1/2)(x)(x+1) \n" ); document.write( "Expand: \n" ); document.write( "36=1/2x^2+1/2x \n" ); document.write( "Multiply by 2 and subtract 72: \n" ); document.write( "x^2+x-72=0 \n" ); document.write( "Factor this: \n" ); document.write( "(x-8)(x+9)=0 \n" ); document.write( "x=8 \n" ); document.write( "x=-0 \n" ); document.write( "So the base is 8 cm and \n" ); document.write( "height is 9 cm \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
