Hope This Helps :)
Answer:
5.600
Step-by-step explanation:
Answer:

Step-by-step explanation:
We have:

To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:

Divide both sides by 2:

Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:

Therefore, our solutions are:

First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry
1st: group the number
(X2+6x)-9
2nd: use b/2
6/2 = 3 , 3^2= 9
(X2+6x+9)-9-9
(X2 + 3)-18
Vertex is 3,-18 so the symmetry is 3
