All sides are equal on a triangle
Answer:
--- Vertex
--- Axis of symmetry
Step-by-step explanation:
Given

Solving (a): The vertex
For an equation written in

The vertex is:

By comparison:
and 

So, the vertex is:

Solving (b): The axis of symmetry
For an equation written in

The axis of symmetry is:
x = h
In (a):

So:

Answer:
a= -2 b =4
Step-by-step explanation:
I put it in a calculator and found the answer
Just count the number of squares:
(9+5)*2=14*2=28
You would have to do 6x2= 12 so it’s 12 outcomes
