A(x)=x^2+5x+6
\n" ); document.write( "A) A(5)=5^2+ 5*5 +6
\n" ); document.write( "=25+25+6
\n" ); document.write( "=56m^2
\n" ); document.write( ".
\n" ); document.write( "B)
\n" ); document.write( "A=.5ab
\n" ); document.write( "56=.5(5+3)b I am assuming that x=5. If it doesn't then ignore this answer.
\n" ); document.write( "4b=56
\n" ); document.write( "b=14m
