PLEASE HELP AND BE REAL I WILL GIVE Simplify 8.7+ (1.5) ²+4(3.5+6.2)-3.1 - 3.5

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′.
