Does anyone understand 1 or 2? Please answer

What is (28 + 7 + 6 + 3) x 1/2 show your work

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′.

Find the value of x. give reasons to justify your solutions! c ∈ ae
