Let's first reformat it:
x2 + y2 - 12x - 8y - 43 = 0
x2 - 12x + 36 + y2 - 8y + 16 = 43 + 36 + 16
(x - 6)2 + (y - 4)2 = 95
So this equation defines a circle, with a center point at (6, 4) and a perimeter (i.e. circumference) of √95.

What does Perimeter sides 2.4 plus 2.4 plus 3.4 equals?
A triangle with sides of 2.4, 2.4 and 3.4, will have a perimeter of 8.1. Remember to include the unit of measure in your answer.
How do you find the area with a perimeter?
Perimeter equals 2 Length plus 2 width so find what l a w is then multiply them
What is the value of k when y equals 3x plus 1 and is a line tangent to the curve of x squared plus y squared equals k?
k = 0.1
What is a perimeter 5 8 plus unknown number equals what?
If a perimeter of 8 is obtained by adding 5 and unknown number, then the unknown number is 3.2.
If you know the perimeter how do you find the area?
Perimeter equals to 2 times the length plus 2 times the breadth. Area equals to length multiply by breadth
What is the perimeter of 7n plus 2 plus 6 plus 5n plus 7n plus 3n equals?
22n + 2.

What is the perimeter of a rectangle with width 3n plus 2 and length n-1?
perimeter equals 2 times width plus 2 times length so, perimeter equals 2(3n+2)+2(n-1) = 6n+6+2n-2 = 8n+4.
What is the value of k when y equals 3x plus 1 and is a line tangent to the curve of x squared plus y squared equals k?
k = 0.1
What is a perimeter 5 8 plus unknown number equals what?
If a perimeter of 8 is obtained by adding 5 and unknown number, then the unknown number is 3.2.
What is the perimeter of a patio if it is modeled by the expression 18 plus 8x and x equals 7?
74 units.
Describe the curve x2 plus y2 equals 25?
A circle, centre (0,0), radius = 5
If Perimeter of a rectangle that has a width of x inches and a length of x plus 16 inches is 2x plus 2x plus 16 inches simplify the expression for the perimeter Find the perimeter if x equals 14?
If the rectangle has a width of x inches, and a length of x + 16 inches, then its perimeter equals to 2x + 2x + 32 or 4x + 32. If x = 14, then x + 16 = 30. So the perimeter of rectangle becomes 2(14) + 2(30) = 28 + 60 = 88 inches.
What is the equation to the tangent line to the curve xy plus y2 equals 0 at the point x equals 3 and y equals 0?
y=0. note. this is a very strange "curve". If y=0 then any value of x satisfies the equation, leading to a curve straight along the y axis. For any non-zero value of y the curve simplifies to y = -x. The curve is not differentiable at the origin.
