Final answer:

To find the length of AE, we derive two equations based on the given midpoints and segment lengths. By solving these equations, we can determine x and y, and then calculate AE by summing the lengths of segments AB, BC, CD, and DE.

Step-by-step explanation:

To figure out the length of AE, we need to establish relationships between the given points and use the information given to solve for the variables x and y.

Firstly, since B is the midpoint of AC, and AC is given as 10x + 3y, then AB, which is half of AC, should be 5x + 1.5y. However, we are also told that AB = 2x + 3y. This creates our first equation:

5x + 1.5y = 2x + 3y

Similarly, D is the midpoint of BE. Thus, CD (which is also half of BE) equals DE. We are given CD = 2x + 4y and DE = 2x + 6y + 20, so now we have our second equation:

2x + 4y = 2x + 6y + 20

Solving these equations provides the values of x and y. Finally, we find AE by adding the lengths AB, BC, CD, and DE, which mathematically translates to:

AE = AB + BC + CD + DE

Upon inserting the values obtained for x and y into this equation, we get the total length of AE.
