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
Thus, AC will also get doubled.

Answer:
1/8 or 0.125
Step-by-step explanation:
Let x be the length of the sides of the square ABCD.
Therefore, the length of CN and CM is x/2.
The area of the triangle MCN is:
The area of the square ABCD is:
Thus, the probability that a random point lies in the triangle MCN is:
The probability that the point will lie in the triangle MCN is 1/8 or 0.125.
