Hello and Good Morning/Afternoon!
<u>Let's take this problem step-by-step</u>:
<u>What the problem asks for:</u>
⇒ to rationalize the denominator
⇒ rationalize means that you multiply the numerator and
demonimator by the denominator
<u>Let's put that into action</u>:
<== <u>Answer</u>
<u></u>
Hopefully that helps!
Multiply by 6 and simplify
.. x = 6*12/9 = 72/9 = 8
x = 8
Answer: 
Step-by-step explanation:
The Slope-intercept form of the equation of the line is:

m: is the slope.
b: the intersection of the line with the y-axis.
The equation of the line
has:

If both lines are parallel, then their slopes are equal. So the slope of the other line is:

To find "b", substitute the given point and the slope into
and solve for "b":

Then the equation of this line is:

The first term is 7. This is because the sequence has a pattern of increasing by 7. If the first term was 7, the second would be 14, the third would be 21. The 4th would be 28, continue to the 8th term 56.
Answer:
the circumference is 31.4159 (or 31.42)
