Answer:
x - 
Step-by-step explanation:
y = x + 10/7
x = y + 10/7
x = y + 10/7
x - 10/7 = y
y = x - 10/7
x - 
Using the formula;

You should get
12.1655 or
12.2 units.
Hope this helps you with Coordinate Solving!
You may notice that all of the terms have a common factor:
. So, let's take the
out of all the terms. This gives us:

Using the Zero Product Property, we can say that both
and
.
Let's solve both.
is obvious, but we still need to solve our other term:



- Apply the Zero Product Property
Our answer is x = -6, 0, 4.
Part A:
The circumference of the circle is 197.92.
Explanation:
The formula for circumference of a circle is C=2 πr. If you insert the numbers, it would be C=2 x 3.14 x 31.5. Hence, the answer is 197.92.
Part B:
The area is 3117.25 square cm.
Explanation:
The formula for area of a circle is A= πr ². Inserting the numbers, it is A=3.14 x 31.5 ². Therefore the answer is 3117.25 cm ².
