Considering the situation described in the problem, the length of segment AD is of: 17 units.
<h3>How to find the length of segment AD?</h3>
From the situation described in the problem, segment AD is divided into three parts:
Then, the length of segment AD is:
AD = AB + BC + CD.
We have that AC = 9, hence:
AB + BC = 9.
We also have that BD = 10, then:
BC + CD = 10.
Since BC = 2, we have that:
- AB + BC = 9 -> AB + 2 = 9 -> AB = 7.
- BC + CD = 10 -> 2 + CD = 10 -> CD = 8.
Then the length of segment AD is given as follows:
AD = AB + BC + CD = 7 + 2 + 8 = 17.

Answer:
- determinant: -15
- x = 3; y = 4; z = 1
Step-by-step explanation:
The matrix of coefficients has one row corresponding to each equation. The constants in that row are the coefficients of the variables in the equation. Coefficients are listed in the same order on each row. A missing term is represented by a coefficient of 0.
<h3>coefficient matrix, determinant</h3>
The first attachment shows the coefficient matrix and its determinant.
__
<h3>solution</h3>
The solution to the system of equations can be found by left-multiplying the constant vector by the inverse of the coefficient matrix.
This multiplication is shown in the second attachment. It tells us ...
