Please help me I don’t really understand it

The perimeter of a rhombus with a side of 6 is 24

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

What is the solution of the equation? 35√(x+2)3+3=27
