Answer:
3(12+27)
Step-by-step explanation: 3 can go into both of those numbers so u would just divide that by 3 with 36 and 81.
Answer:
The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
Step-by-step explanation:
The average speed is given by the following equation:
![v = \frac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
From 10A.M. to noon.
You traveled at 50mph during 2 hours. So how long you traveled?
![50 = \frac{d}{2}](https://tex.z-dn.net/?f=50%20%3D%20%5Cfrac%7Bd%7D%7B2%7D)
![d = 50*2](https://tex.z-dn.net/?f=d%20%3D%2050%2A2)
![d = 100](https://tex.z-dn.net/?f=d%20%3D%20100)
You traveled 100 miles.
What was your average speed over the time interval from 9 A.M. to noon
From 9 A.M. to 10 A.M, you did not travel.
From 10 P.M. to noon, 100 miles.
So 100 miles during 3 hours.
![v = \frac{d}{t} = \frac{100}{3} = 33.33](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B100%7D%7B3%7D%20%3D%2033.33)
The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
x^2 + 6xy + 8y2
4x^2 + 3xy + 2y^2 - 5x^2 + 2xy + 6y^2
= 4x^2 + 3xy + 2y^2 + -5x^2 + 3xy + 6y^2
Combine like terms:
= 4x^2 + 3xy + 2y^2 + -5x^2 + 3xy + 6y^2
= (4x^2 + -5x^2) + (3xy + 3xy) + (2y^2 + 6y^2)
= -x^2 + 6xy + 8y^2
Which of the following is a composite number?<span>A. 19
B. 63
C. 1
D. 0
63 is a composite number because it is a </span><span>whole number that can be divided evenly by numbers other than 1 or itself.</span>
