2c is a factor of both terms.
.. area = 2c(c+1)
Possible expressions for length and width are
1, 2, c, 2c, c+1, 2(c+1), c(c+1), 2c(c+1).
Step-by-step explanation:
(14)
Since the rope encloses the circular pool.
Therefore, circumference of pool c = 94.2 inches
Circumference of circle is given by the formula:

Okay so you have to do
138 times .40-move the decimal over 2 times
that is 55.2 so 40 percent of 138 is 55.2 so add that on to 138 to get 192 students at the school. There you go :)
A number - n
five times the number - 5n
nine more than five times the number - 5n+9
The answer is D.
