Answer: B
Because...
3x + 2x < -2x + 2x + 7
5x < 7
So you have to do addition BEFORE division.
Answer:
![-6x^3y^5](https://tex.z-dn.net/?f=-6x%5E3y%5E5)
Step-by-step explanation:
![3xy^2\left(-2x^2y^3\right)](https://tex.z-dn.net/?f=3xy%5E2%5Cleft%28-2x%5E2y%5E3%5Cright%29)
Simplify
___________
Apply the negative rule
:
![-3xy^2\cdot \:2x^2y^3](https://tex.z-dn.net/?f=-3xy%5E2%5Ccdot%20%5C%3A2x%5E2y%5E3)
Add exponents :
![-3x^{1+2}y^2\cdot \:2y^3](https://tex.z-dn.net/?f=-3x%5E%7B1%2B2%7Dy%5E2%5Ccdot%20%5C%3A2y%5E3)
![-3x^3y^2\cdot \:2y^3](https://tex.z-dn.net/?f=-3x%5E3y%5E2%5Ccdot%20%5C%3A2y%5E3)
Add exponents once again :
![-3x^3y^{2+3}\cdot \:2](https://tex.z-dn.net/?f=-3x%5E3y%5E%7B2%2B3%7D%5Ccdot%20%5C%3A2)
![-3x^3y^5\cdot \:2](https://tex.z-dn.net/?f=-3x%5E3y%5E5%5Ccdot%20%5C%3A2)
Multiply the whole number by the variable expression :
![-6x^3y^5](https://tex.z-dn.net/?f=-6x%5E3y%5E5)
Answer:
The answer is
![- 7.95](https://tex.z-dn.net/?f=%20-%207.95)
Step-by-step explanation:
![15.9x + c = 5.3(3x - 1.5) \\ 15.9x + c = 1.9x - 7.95 \\ c = - 7.95](https://tex.z-dn.net/?f=15.9x%20%2B%20c%20%3D%205.3%283x%20-%201.5%29%20%5C%5C%2015.9x%20%2B%20c%20%3D%201.9x%20-%207.95%20%5C%5C%20c%20%3D%20%20-%207.95)
TO find:
The area of a rectangle whose height is 17cm and the breadth is 8cm.
Solution:
It is known that the area of a rectangle is given by:
![A=l\times b](https://tex.z-dn.net/?f=A%3Dl%5Ctimes%20b)
So, the area of the given rectangle is:
![A=17\times8=136cm^2](https://tex.z-dn.net/?f=A%3D17%5Ctimes8%3D136cm%5E2)
Thus, the area of the rectangle is 136 cm^2.
