Answer:
![9k^{3} -3k^{2}-29k-12](https://tex.z-dn.net/?f=9k%5E%7B3%7D%20-3k%5E%7B2%7D-29k-12)
Step-by-step explanation:
Step 1: Expand by distributing sum groups.
![3k(3k^{2} -5k-3)+4(3k^{2} -5k-3)](https://tex.z-dn.net/?f=3k%283k%5E%7B2%7D%20-5k-3%29%2B4%283k%5E%7B2%7D%20-5k-3%29)
Step 2: Expand by distributing terms.
![9k^{3} -15k^{2} -9k+4(3k^{2} -5k-3)](https://tex.z-dn.net/?f=9k%5E%7B3%7D%20-15k%5E%7B2%7D%20-9k%2B4%283k%5E%7B2%7D%20-5k-3%29)
Step 3: Expand by distributing terms.
![9k^{3}-15k^{2} -9k+12k^{2} -20k-12](https://tex.z-dn.net/?f=9k%5E%7B3%7D-15k%5E%7B2%7D%20-9k%2B12k%5E%7B2%7D%20-20k-12)
Step 4: Collect like terms.
![9k^{3}+(-15k^{2} +12k^{2} )+(-9k-20k)-12](https://tex.z-dn.net/?f=9k%5E%7B3%7D%2B%28-15k%5E%7B2%7D%20%20%2B12k%5E%7B2%7D%20%29%2B%28-9k-20k%29-12)
Step 5: Simplify.
![9k^{3} -3k^{2}-29k-12](https://tex.z-dn.net/?f=9k%5E%7B3%7D%20-3k%5E%7B2%7D-29k-12)
Answer:
A. 1/5k - 2/3j and -2/3j +1/5k
Step-by-step explanation:
A. 1/5k - 2/3j and -2/3j +1/5k
B. 1/5k - 2/3j and -1/5k +2/3j
There is a change in the signs of each term
1/5k changed to -1/5k
-2/3j changed to +2/3j
Not equivalent
C. 1/5k - 2/3j and 1/5j - 2/3k
There is a change in the variables
1/5k changed to 1/5j
-2/3j changed to -2/3k
D. 1/5k - 2/3j and 2/3j - 1/5k
The is a change in the signs of each term
1/5k changed to -1/5k
-2/3j changed to +2/3j
The only equivalent expression is
A. 1/5k - 2/3j and -2/3j +1/5k
