Answer:

(-7,4)

Step-by-step explanation:

goal: (y-k)^2=4p(x-h)

y^2-8y=4x+12 Rearranged and added 4x and 12 on both sides

y^2-8y+(-8/2)^2=4x+12+(-8/2)^2 complete square time (add same thing on both sides)

y^2-8y+(-4)^2=4x+12+(-4)^2 (simplify inside the squares)

(y-4)^2=4x+12+16 (now write the left hand side as a square)

(y-4)^2=4x+28

(y-4)^2=4(x+7) factored...

vertex is (-7,4)

I think it’s b but I may be wrong

leonid [27]

Answer:

D, not B

Step-by-step explanation:

So using Pythagorean Theorem:

$C^{2} =A^{2} +B^{2} \\x^{2} =144+265\\x^{2} =400\\x=20$

Yep, It's not B, But D.

Hope this helps!
