Choose all of the equations that represent a parabola with the focus (0,4) and the vertex (0-6). A = 20 (y + 1)
B. = 40 (y +6)
c. 20y = 2 – 20
D. 40y = (x + 62
E. 40y = - 240

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

Landon wrote that 3−2.6=4. which statement about his answer is true?

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142
