You halve the linear coefficient, square it, then add that to both sides. In this case:
(12/2)^2=6^2=36 so you would add 36 to both sides
x^2+12x+36=76 so that the left side is now a perfect square
(x+6)^2=76
The radius is 4. All u have to do is divide the diameter of the circle by 2

Answer: 9 pizzas
Step-by-step explanation:
From the question, we are informed that Jackson Elementary School ordered 25 pizzas for an awards ceremony and at the end of the day, the principal found 8 1/4 pepperoni pizzas and 7 3/4 sausage pizzas left over.
A reasonable estimate for the number of pizzas the students ate at the awards ceremony will be:
= 25 - (8 1/4 + 7 3/4)
= 25 - 16
= 9 pizzas
Answer:
y = -4x + 64.
Step-by-step explanation:
The slope is rise / run = (64-0) / (0-16)
= 64 / -16
= -4.
The y-intercept is y = 64 so the equation is
y = -4x + 64.
