Any with an odd number of minus signs.
Perhaps the 1st and 4th, if I read it right.
I'm not sure if it's 10x or 10 times a number
The equation of a circle with radius of 6 units and center on the x axis could be (x - 6)² + y² = 36
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The circle has a diameter of 12 units. Hence, radius = 12/2 = 6 units.
The center of the circle is at x axis (*, 0), the equation could be:
(x - 6)² + (y - 0)² = 6²
(x - 6)² + y² = 36
