Question

1. the distance because a - b - c, ab + bc = ac, or 7 + 5 = 12, according to the betweenness of points theorem. use the betweenness of points theorem to complete the following statements. 9. because b - c - d, bc+? =?, or 5 +? =?.

Explanation:

Step1: Apply Betweenness of Points Theorem

According to the theorem, if B - C - D, then \(BC+CD = BD\).
If \(BC = 5\), let \(CD=x\) and \(BD = y\), so \(5 + x=y\).

Answer:

Because B - C - D, \(BC + CD=BD\), or \(5+CD = BD\)
