Question

if b is between a and c, and ab = 5 and bc = 7, then what is the length of ac?
○ 35
○ 12
○ 1.4
○ 2

Explanation:

Step1: Apply segment addition postulate

Since B is between A and C, $AC = AB + BC$

Step2: Substitute given values

$AC = 5 + 7$

Step3: Calculate the sum

$AC = 12$

Answer:

12 (Option: 12)
