Assume it's:
\n" ); document.write( "The radius of a circle is 8 cm.
\n" ); document.write( "(3x + 1) represents the length of the diameter.
\n" ); document.write( "Write an equation for x.
\n" ); document.write( "\"%28%283x%2B1%29%29%2F2\" = 8
\n" ); document.write( " Then find the value of x.
\n" ); document.write( "3x + 1 = 2(8)
\n" ); document.write( "3x = 16 - 1
\n" ); document.write( "3x = 15
\n" ); document.write( "x = 15/3
\n" ); document.write( "x = 5
\n" ); document.write( "
\n" );
