Which of the following statements about 42xy – 49x + 30y – 35 are true? Check all of the boxes that apply.

Group the terms: (42xy − 49x) + (30y − 35). Factoring each group gives 7x(6y − 7) + 5(6y − 7), so the full expression factors as (7x + 5)(6y − 7). Therefore, (7x + 5) and (6y − 7) are factors.
