Answer:
The answer is d
Step-by-step explanation:
I graphed it
-b/2a to get the vertex
3x^2-12+9
-(-12)/(2)(3)=2
plug in 2 to the function
12-24+9=-3 which is the y value on the graph
(2,-3) is the vertex
The perimeter would just be the equation that they provided to you multiplied by 3 because a triangle has 3 sides, and it is an equilateral triangle, so every side is the same. You do the distributive property to solve the equation and get your final answer.
These are the angle measurements, hope this helps you and let me know if im wrong
