9/n+2=2/6 How do I solve for n?

What signals you that factoring by grouping is the best method to use when factoring a problem?

Can someone me with this problem . show your work .

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
