Answer:
Step-by-step explanation:
Simplified expression:
![3x^3 -x^3 +5x^3-9x^3](https://tex.z-dn.net/?f=3x%5E3%20-x%5E3%20%2B5x%5E3-9x%5E3)
![2x^3 +5x^3-9x^3](https://tex.z-dn.net/?f=2x%5E3%20%2B5x%5E3-9x%5E3)
![7x^3 -9x^3](https://tex.z-dn.net/?f=7x%5E3%20-9x%5E3)
![-2x^3](https://tex.z-dn.net/?f=-2x%5E3)
If x = -1, the value of the expression is:
![-2x^3](https://tex.z-dn.net/?f=-2x%5E3)
![-2(-1^3)](https://tex.z-dn.net/?f=-2%28-1%5E3%29)
![-2(-1)](https://tex.z-dn.net/?f=-2%28-1%29)
![2](https://tex.z-dn.net/?f=2)
Hope this helps!
