Answer:

D

Step-by-step explanation:

if you simplify 7k+2k−1 you will end up with the answer of 9k-1 therefore you can take out statement A and B

For C it is also wrong because when you substitute k with the same number for both expressions you will get different answers Therefore your answer you are looking for is D
