STREAM WALLS BY LOUIS TOMLINSON

Which expression calculates the speed in meters per second of an object that travels a distance of 100 m every 20 seconds

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′.

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?
