Answer:
C
Step-by-step explanation:
Given
The numerator is a difference of squares
x² - 16 = (x - 4)(x + 4)
= 
← cancel the common factor (x + 4) on numerator/ denominator
= 
→ C
Answer:
2.25 radians
Step-by-step explanation:
First we need to find the length of the circunference, using the formula:
C = 2 * pi * r
Where r is the radius. Using r = 8, we have:
C = 2 * pi * 8 = 50.2655 cm
Now, to find the measure of the central angle related to that arc of 18 cm, we can use a rule of three, knowing that the whole circunference has a central angle of 2pi radians:
2pi rad -> 50.2655 cm
x -> 18 cm
x = 18 * 2pi / 50.2655
x = 2.25 rad
Answer:
5400
Step-by-step explanation:
60 min=1 hour
120 min=2 hr
120 x 45=5400
Answer:
it is 20% your welcome
Step-by-step explanation:
because when you divide 100 by 2 its 50 so its 20%
Make sure the number is rational if it isn’t
