Answer:
b
Step-by-step explanation:
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
The answer is that c3x was the answer
Step-by-step explanation:
7+8+10=25cm is the possibile perimeter of this
triangle.
