p=-7
Answer:
Step-by-step explanation:
If this was an entire circle, the area could be found by using
Area = pi * r^2 where r = 9
To take the central angle into account, use this formula
Area = 120/360 * pi * r^2
Area = 1/3 * pi * 9^2
Area = 27 pi
area = 84.78 cm^2 which isn't there.
Answer:
A and B is correct
Step-by-step explanation:
Answer:
-5x^2-2x
Step-by-step explanation:
When distributing, you multiply the term outside the brackets to all the terms in brackets.
If the term outside the bracket is negative, then when distributing/opening the brackets, the signs of the terms changes.
So in this prob. -x would multiply to both +5x and +2
-x*5x+-x*2
∴-5x^2-2x
60 minutes for 2 times of 4.5 miles
60 minutes for 9 miles.
9 miles/60 minutes = 9 miles/1 hour
9 mph
