Here, it means ...

Answer:
P = 30
A = 22
Step-by-step explanation:
Find perimeter first
P = 5 + 5 + 2 + 2 + 2 + 2 + 2 + 2 + 4 + 4
P = 10 + 12 + 8
P = 30
Now area
A = 2(5 * 2) + (2 * 1)
A = 2(10) + (2)
A = 20 + 2
A = 22
Answer:
x = 21
Step-by-step explanation:
1/3(x + 6) = 1/2(x - 3)
(3)1/3(x + 6) = (3) 1/2(x - 3) - multiply both sides by 3 to get rid of the 1/3
x + 6 = 3/2(x - 3)
x + 6 = 3/2 (-9/2) - i distributed the 3/2 into the parenthesis
x + 6 (2) = 3/2 (-9/2) (2) - multiply each side by 2 to get rid of the fractions
2x + 12 = 3x - 9
2x - 3x = -12 -9 - bring the x to one side
-x = -21
-x/-1 = -21/-x
x = 21

Option A:
is the equation of the circle
Explanation:
The equation of the circle is 
We need to write the equation of the circle in standard form.
Let us subtract 10 from both sides of the equation.
Thus, we have,

Grouping the terms,we have,

Now, we shall complete the square, let us add and subtract the equation by 9 to write the term
in the form of 
Thus, we have,

Simplifying, we get,


Similarly, we shall complete the square for the term
in the form of 
Thus, we have,

Simplifying, we get,


Thus, the equation of the circle in standard form is 
Hence, Option A is the correct answer.
