Find the distance between the points B and B′ if ΔABC is reflected across line l followed by a reflection across line m. A.)10 units
B.)14 units
C.)7 units
D.)17 units

¿Consideras que la gente que discrimina por aspectos como el color de la piel, clase social, por el género, etc., no saben lo que las personas valen y por eso no las valoran?

14 units

Step-by-step explanation:

If l and m are two parallel lines and a point X is reflected across line l followed by a reflection across line m, then the distance between

X and X′ is 2d, where d is the distance between l and m. Since d = 7, the distance between B and B′′ is 2(7) = 14 units.

the answer is d
