What is the measure of angle 2z (pic in question)

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Evaluate the expression. (9 + 5)(3 + 2)0
