<em>You would use AAS because of the fact that there is two angles and the angle where both triangles instersect and create a verticle angle, there is no angle written. It has an angle then another angle then a side. Hope this helps!</em>
F(x)=x(3x+5) or f(x)=3x²+5x Here the domain in general is: -∞<x<∞ But the length of the rectangle cannot be negative, therefore the domain is all real numbers greater than zero.
