You can put this solution on YOUR website!
A = 1/2 times base times height\r
\n" ); document.write( "\n" ); document.write( "Let A = 21\r
\n" ); document.write( "\n" ); document.write( "Let h = height = (x - 5)\r
\n" ); document.write( "\n" ); document.write( "Let b = base = x\r
\n" ); document.write( "\n" ); document.write( "21 = 1/2 times x times (x - 5)\r
\n" ); document.write( "\n" ); document.write( "I gave you the equation. Can you finish now?
