- Vertex form:
, with (h,k) as the vertex.
For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:
Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:
Putting our equation together,<u> it's 
</u>

- Standard form:
Converting to standard form as such:
1) 18
2) 4
3) 27
4) 9
5) x=8
6) x=6
Answer:
By using the formula: 
*b*h
Answer:
A
Step-by-step explanation:
-Nx + 6 > 12 (subtract 6 on both sides)
-Nx > 6 (Divide by N on both sides)
-x > 
(divide by negative) (When you divide by a negative you flip the sign)
x < -
Answer:
B. 
Step-by-step explanation:
The sides forming the right angle are called the legs. Since the two angles shown are congruent, the legs are congruent.
We can use the Pythagorean theorem.
