Answer: 
Step-by-step explanation:
The standard form of a circle is written as such:

Where (h, k) is the center of the circle, and r is the radius.
We know that the center is (-7, 0), so we can plug that into the equation like this: 
The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:

So, your standard form equation is the following:

Answer:
8 out of 11
Step-by-step explanation:
Answer:
X-6
Step-by-step explanation:
Represent the unknown number with a variable then introduce the minus sign
The equation has three factors and equals zero
One of the factors must be zero.
Either 3x = 0 which means x = 0
or x - 4 = 0 which means x = 4
or 3x + 5 = 0 which means 3x = -5 so x = -5/3
The answer is C
E cannot be correct in this question as you are asked to “solve” and not just pick a correct option
Answer:
The answer is A
Step-by-step explanation:
25/45
= (25÷5)/(45÷5)
= 5/9
