Plsss answer these show work

Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4? a.)y-3 = 1/16 (x-2)^2 b.)y+3 = -1/16 (x+2)^2 c.)x-2 = 1/16 (y-3)^2

Ineeeeed this is due tomorrow and i dont know the answer can you find all the exponents

Solve the equation. 2x - 8(x+1)= 6(2x - 3)
