I would say triangle. But I am not completely sure!
Step-by-step explanation:
Hope this helps!
-3x^2 + 12x -6
a = -3
b = 12
We calculate the vertex "x" value with this formula:
(vertex "x value") = -b / (2*a)
(vertex "x value") = -12 / -6
The vertex "x" value equals the axis of symmetry value.
The axis of symmetry is at x = 2.

Answer:
1152
Step-by-step explanation:
Multiply 3200 * 0.045
144 * 8=1152
4x -(9-3x) = 8x-1
4x -9 + 3x = 8x-1
7x-9 = 8x-1
-9 + 1 = 8x-7x
-8 = x
x = -8
Five. 7-2 is five. you are welcome lol
