Answer: AC will also be doubled.
Step-by-step explanation: Given that point B lie between A and C on AC. AB is doubled and BC is also doubled.
We are to find the effect on AC.
Let us consider that
AB = x and BC = y ⇒ AC = AB + BC = x + y.
Then, being doubled, we get
AB = 2x and BC = 2y.
Therefore, we get
\(AC=AB+BC=2x+2y=2(x+y).\)
Thus, AC will also get doubled.
