Jane and Jill were simplifying the expression

(2x² + x) + 21-x² + x) and obtained different answers. Who is

correct and why?

What is the first step of an indirect proof of a number that is divisible by two

What are the first 4 terms in the multiplication pattern given by the formula 2×4n

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′.
