The vertical distance between B and C can be found by taking the absolute difference of their y-coordinates. Using the given coordinates:

B = (7.5, 2)

C = (7.5, -2.5)

The vertical distance between B and C is given by:

| y-coordinate of B - y-coordinate of C |

= | 2 - (-2.5) |

= | 2 + 2.5 |

= | 4.5 |

= 4.5

So, the expression representing the vertical distance between B and C is simply 4.5.
