Question

(3t+9)+(3t–6)

Answer 1

To add the expressions \( (3t + 9) + (3t - 6) \), you can combine like terms:

1. Combine the \( t \) terms: \( 3t + 3t = 6t \).
2. Combine the constant terms: \( 9 - 6 = 3 \).

Putting it all together, the result is:

\[ 6t + 3 \]

So, \( (3t + 9) + (3t - 6) = 6t + 3 \).
