19 liter equivalent to? cubic decimeter
I am in Secondary 3
How do we know the equivalent of the 19 liter to the cubic decimeter?

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′.

Math it's appreciated. (picture provided)

Which expression gives the exact value of x?
