The name of the angle is obtuse
The vertex is 
Explanation:
The equation is 
To find the vertex, we need the equation in the form of 
Dividing each term by 2 in the equation
Now, completing the square by adding and subtracting 1, we get,
The first three terms can be written as 
,
![f(x)=2[(x+1)^{2}+\frac{1}{2} ]](https://tex.z-dn.net/?f=f%28x%29%3D2%5B%28x%2B1%29%5E%7B2%7D%2B%5Cfrac%7B1%7D%7B2%7D%20%20%5D)
Multiplying 2 into the bracket, we get,
This equation is of the form
Now, we shall find the vertex 
Thus, 
and 
Thus, the vertex is

Options :
A) 12⟌60
B) 60 ÷ 12
C) 60⟌12
Answer:
C) 60⟌12
Step-by-step explanation:
Given that :
Total cost of inviting 12 guests to a party = $60
To obtain the cost per guest :
Total cost of invitation / number of guests
That is ; we divide the cost of inviting the guests by the number of guests invited
$60 / 12 = 12⟌60
The expression 60⟌12 is incorrect as this means 12 / $60
