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.

You have to simplify each equation. You can do that by adding similar values to each other:
(the first equation)
8x²y + 7x² - 5y² + 3x - 2 + 2x²y - x² - 2y² + 3x - 4
To make it easier, arrange the values around so that similar ones are beside each other:
8x²y + 2x²y + 7x² - x² - 5y² - 2y² + 3x + 3x - 2 - 4
then add the similar values together:
8x²y + 2x²y = 10x²y
7x² - x² = 6x²
- 5y² - 2y² = -7y²
3x + 3x = 6x
(- 2)+ (- 4) = -6
and if you put them together:
10x²y + 6x² - 7y² + 6x - 6
This isn't the answer to the equation, because it's different. So repeat the process with all the other equations until you find one that is identical to the simplified version.
The answer is the second one: 8x²y + 7x² - 5y² + 3x - 2 + 2x²y - x² - 2y² - 3x - 4

Answer:
Why is | 7 | the absolute value of the number 7?
The absolute value of a number is how far away the number is from zero. The absolute value is ALWAYS positive.
What is the absolute value of -7?
The negative version of the number is also | 7 |
