F(x) = 0 polynomial or not

From the figure and statement provided, select the proper to prove statement. through a point outside a line one line can be drawn parallel to the line. mn= ab ab + bc= ac mis parallel to ! ab=bc als parallel to b

1. are the triangles similar and if so why? what is the value of x? show your work.

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6
