You can put this solution on YOUR website! 23)
(x+5)(x+7)
x^2+7x+5x+35
x^2+12x+35
------------------------------
29)
-3x+4>7
-3x>7-4
-3x>3
x<3/-3
x<-1
proof:set x=-2
-3*-2+4>7
6+4>7
10>7
---------------------------------------
31)
the first and last set are not functions.
---------------------------------------
36)
this is a 4th degree equation.
