O 14k + 13
To add 9(k + ‡) + 10(‡k - 1), we can distribute the 9 and the 10 to the terms inside the parentheses:
9(k) + 9(‡) + 10(‡k) - 10(1)
This simplifies to:
9k + 9‡ + 10‡k - 10
To combine like terms, we can add the coefficients of similar variables:
(9k + 10‡k) + (9‡ - 10)
This further simplifies to:
(9 + 10)k + (9‡ - 10)
Finally, combining the coefficients:
19k + (9‡ - 10)
Therefore, the sum of 9(k + ‡) + 10(‡k - 1) is 19k + (9‡ - 10).
