Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given (h, k) = (0, - 7) and r = 11, then
(x - 0)² + (y - (- 7))² = 11², that is
x² + (y + 7)² = 121 → A
Sorry mahne put it in english so i understand more :)
Equations are statements that have equal values, when compared
The true statement about 
are x = 1 and x = -11
<h3>How to determine the true statement</h3>
The equation is given as:
Rewrite as:
Expand
Factorize
Factor out x + 11
Solve for x
x = 1 or x = -11
Hence, the true statement about are x = 1 and x = -11

Answer:
x = -4
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, divide 3 from both sides of the equation:
(3(-3 - 3x))/3 = (27)/3
-3x - 3 = 27/3
-3x - 3 = 9
Next, isolate the variable, x. Note that what you do to one side of the equation, you do to the other. Do the opposite of PEMDAS.
First, add 3 to both sides:
-3x - 3 (+3) = 9 (+3)
-3x = 9 + 3
-3x = 12
Next, divide -3 from both sides:
(-3x)/-3 = (12)/-3
x = 12/-3
x = -4
x = -4 is your answer.
