Answer:
C.
Step-by-step explanation:
As the center is (-6, -8) the 2 factors on the left will be (x + 6) and (x + 8) so it's either A or C.
When x = 0 y = -8 so substituting we have:
(0 + 6)^2 + (-8 + 8)^2 = 36 + 0 = 36.
So it's choice C.

63 cause there equal
Step-by-step explanation:
X^2 + 6x - 27
(x - 3)(x + 9)
The answer is: (x - 3)(x + 9).
Answer:
x = 1.434 and x=0.232
Step-by-step explanation:
To find the root of the equation stated above we need to:
(1) Write the polynomial equation with zero on the right hand side:
⇒ 
(2) Divide the whole equation by 3
⇒ 
(3) Use the quadratic formula to solve the quadratic equation:
The quadratic formula states that the two solutions for a quadratic equation is given by:
(1)
In this case, a = 1, b = 
Substituiting a, b and c in equation (1) We get:
(1)
The two solutions are:
x = 1.434 and x=0.232
Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers. If a number is terminating or repeating, it must be rational if a decimal is both non terminating and non repeating, the number is irrational.
So yes.
