Considering the given equation of the circle, the true statements are given as follows:
- The radius of the circle is of 3 units.
- The center of the circle lies on the x-axis.
- The circle has the same radius as the circle with equation x² + y² = 9.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center
and radius r is given by:

The equation given is:
x2 + y² - 2x - 8 = 0.
Completing the squares, the equation is given as follows:
(x - 1)² + y² = 8 + 1
(x - 1)² + y² = 9.
Researching the problem on the internet, the true statements are:
- The radius of the circle is of 3 units.
- The center of the circle lies on the x-axis(
).
- The circle has the same radius as the circle with equation x² + y² = 9.

Answer:
400 square yards
Step-by-step explanation:
square part = l x w = 20 x 15 = 300
triangle part = 1/2 b x h = 1/2 (20) (10) = 100
300 + 100 = 400
Ok if there is 423 dogs and 56 big dogs need to sub the dogs and you get
423-56=357 big dogs
SO there are 357 dig dogs
