Answer:
A. (2, -3).
Step-by-step explanation:
The first step is to complete the square on the terms in x and the terms in y:
x² - 4x +4 +y² +6y + 9 =4
= (x - 2)² - 4 + (y + 3)² - 9 + 4 + 9 = 4
= = (x - 2)² + (y + 3)² - 9 + 9 - 4 + 4 = 4
= (x - 2)² - (y + 3)² = 4.
So the centre is at (2, -3).
We are given that:
one person would eat 3/8 of a pizza.
To know the number of people that would eat 12 pizzas, all you have to do is cross multiplication as follows:
1 person .............> 3/8 pizza
?? person ............> 12 pizzas
Number of people = (12*1) / (3/8) = 32 people
Answer: 
Step-by-step explanation:
Suppose the missing polynomial be f(x)
So, we can write
The correct answer is B 98.4 divided by 4.8, and you get 20.5
