If the diameter of a circle changes from 5 cm to 15 cm, how will the circumference change? a. multiplies by 1/3 b. multiplies by 3 c. increases by 10 d. decreases by 10 and give the correct answer.

Thelime contains the point(-3,0) and parallel x-3y=3( show all 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′.
