The expression ( a + 2 b + 3 c ) − ( 4 a + 6 b − 5 c ) simplifies to − 3 a − 4 b + 8 c , which corresponds to option E.

Jawaban:12. B. he will be giving a lecture This is the correct option because it uses the future continuous tense, indicating an action that will be in progress at a specific time in the future (tomorrow). The other options are grammatically incorrect. 13. C. She must have studied hard last night. This option expresses deduction about a past event. Brenda's high score suggests she likely studied hard. "Must have" indicates a strong probability. The other options don't express this logical deduction as well. 14. A. to finish quickly The sentence compares two actions using infinitives. The structure is parallel and grammatically correct. The sentence implies that accuracy is prioritized over speed. Option B is incomplete.
