Answer:
Because it is a rectangle, the top and the bottom are different lengths than the sides. So therefore 6 chairs cannot fit on every sides.
Step-by-step explanation:
72 degrees.
Explanation:
Pentagon = 5 sides.
360 degrees (degrees of a full circle) divided by 5 (sides of the pentagon) equals 72 degrees.
A5+b5=(a+b)(a4-a3b+a2b2-ab3+b4)
If you mean, "does the sequence

converge", then yes, since

.
If you mean, "does the series

converge", then no, for the reason above (the summand passes the nth limit test for divergence, so the series diverges).
