13, -7, -1, 0, <, >, 66, -12
A reasonable domain would be [0, 8] since 8 hour work days are common.
A reasonable range would then be [0, 64].
Question 3:
50-3n=5
therefore,
50-5=3n
45=3n
n=45/3
n=15
The 15th term of the sequence has a value of 5.
sorry i am not sure about the rest, i am new to this topic and have just started learning it.

- And if c² = a² + b², then we have a right triangle.
Where c is the longest side, and a and b are the two remaining sides.


(16 is less than 9 + 9 or 18.)


(25 is equal to 9 + 16 = 25.)
