Three friends went to a ballgame. Each bought a ticket for $8 and they shared a bag of peanuts that cost $5. Which expressions represent how much they spent in all?

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′.

Can you me find the missing length. i attached an image.
