Help please I need help :/

The triangles are similar. what is the value of x? show your work.

Which of the following equations is of the parabola whose vertex is at (4, 3), axis of symmetry parallel to the y-axis and focus at (4, -3)? a.) y+3=1/24 (x+4)^2 b.)y-3=-1/24 (x-4)^2 c.)x-4=-1/24 (y-3)^2

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)
