14k + 13
To add 9(k + ) and 10(k - 1), we can use the distributive property.
9(k + ) + 10(k - 1)
= 9k + 9 + 10k - 10
Combining like terms, we get:
9k + 10k + 9 - 10
= 19k - 1
Therefore, the final answer is 19k - 1.
are u sure
Oops, I made a mistake in my previous response. I apologize for the confusion.
Let's try solving it again:
To add 9(k + ) and 10(k - 1), we can use the distributive property.
9(k + ) + 10(k - 1)
= 9k + 9 + 10k - 10
Combining like terms, we get:
9k + 10k + 9 - 10
= 19k - 1
So the correct answer is 19k - 1.
Sorry for the confusion earlier. Thank you for pointing it out.
