![3m^2n+12mn^2](https://tex.z-dn.net/?f=3m%5E2n%2B12mn%5E2)
In both the sets, 3 and m as well as n can be found as common factors.
So,
3mn( m+4n)
Therefore the answer is 3mn (#3)
Answer:
No.
Step-by-step explanation:
Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6, we should get a true equation.
y = 3x - 6
-9 = 3 * 1 - 6
-9 = 3 - 6
-9 = -3.
So, the points (1, -9) does not satisfy the equation y = 3x - 6.
6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not.
24-6=18. Thus, the ratio would be 6:18
Answer:
3872/(x^2 - 2)
Step-by-step explanation:
Simplify the following:
(16^3 - 3^2 - 5×43)/(x^2 - 2)
3^2 = 9:
(16^3 - 9 - 5×43)/(x^2 - 2)
16^3 = 16×16^2:
(16×16^2 - 9 - 5×43)/(x^2 - 2)
| 1 | 6
× | 1 | 6
| 9 | 6
1 | 6 | 0
2 | 5 | 6:
(16×256 - 9 - 5×43)/(x^2 - 2)
16×256 = 4096:
(4096 - 9 - 5×43)/(x^2 - 2)
43 (-5) = -215:
(4096 - 9 + -215)/(x^2 - 2)
4096 - 9 - 215 = 3872:
Answer: 3872/(x^2 - 2)
Answer:
Max exercises 13 hours a week, and Sasha 7.
Step-by-step explanation:
To find the number of hours each of them exercises during the week, we solve the system of equations.
In the second equation:
![x = 4y - 15](https://tex.z-dn.net/?f=x%20%3D%204y%20-%2015)
Replacing in the first equation:
![x + y = 20](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2020)
![4y - 15 + y = 20](https://tex.z-dn.net/?f=4y%20-%2015%20%2B%20y%20%3D%2020)
![5y = 35](https://tex.z-dn.net/?f=5y%20%3D%2035)
![y = \frac{35}{5}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B35%7D%7B5%7D)
![y = 7](https://tex.z-dn.net/?f=y%20%3D%207)
So Sasha exercises 7 hours per week.
Max:
![x + y = 20](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2020)
![x + 7 = 20](https://tex.z-dn.net/?f=x%20%2B%207%20%3D%2020)
![x = 13](https://tex.z-dn.net/?f=x%20%3D%2013)
Max exercises 13 hours a week.
