She has been with her book club for 49 months.
Step-by-step explanation:
Books read = 12 books
Time period = 7 months
Therefore,
12 books = 7 months
1 book =
Books read so far = 84 books
Total time period = x
84 books = x months
1 book = 
Using both unit rates;

Answer: 36 customers
Step-by-step explanation:
I'm pretty sure because you have to multiply 40 x 6 which is 240 and 6 x 6 which is 36 to get your answer.
The area of a rectangle is calculated as length times its width. So, for the given area above, the expression should b written as:
20 = LW
To know the length for various measurement of the width, we can write it by:
L = 20 / W
You can substitute any measurement to W and you can obtain the corresponding value of the length.

So roots of a equation are imaginary
81k^2 - m^2 factors to
(9k + m)(9k - m)
Prove this by FOILing.
First - 81k^2
Outer - (-9km)
Inner - 9km
Last - (-m^2)
Put it into equation form
81k^2 - 9km + 9km - m^2
And combine terms to get the original equation,
81k^2 - m^2.
