Step-by-step explanation:
(x²-1)(x+1)≥0
As it has two multiples,
Therefore,
Either,
x²-1≥0
x²≥0+1
x²≥1
x≤√1
x≤1
Or,
x+1≥0
x≥-1

Answer:
25.12 millimeters is your answer.
Step-by-step explanation:
Circumference can be solved by using the equation:
c = 2πr or c = πd
Note that diameter (d) is equal to 8. Plug in 8 for d.
c = (8)(π)
Also note that π = 3.14. Multiply
c = (8)(3.14)
c = 25.12 millimeters.
25.12 millimeters is your answer.
