Help geometry. find bdc

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′.

Table which ratio is equivalent to 3: 7? 6: 7 3: 21 24: 56 15: 30

(: the two box-and- whisker plots below show the scores on a math exam for two classes. what 2 things do the interquartile range tell you about the two classes?
