15. The table below shows the number of rectangular tiles needed to cover square shaped floors with certain side lengths. If the number of
tiles is proportional to the area of the floor, how many tiles would be
needed for a square shaped floor with a side length of 9 feet?

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′.
