The measure of segment AB is 2x-3 and the measure of segment BD is 5x-6.
If you want to find the measure of segment AD you have to add up AB and BD

So [tex]2x-3+5x-6[/tex], combine like terms 2x+5x equals 7x and -3-6 equals -9, so the measure of segment AD is [tex]7x-9[/tex]

Answer:

18

Step-by-step explanation:

Since AB ≅ BD that means they equal the same

2x + 3 = 5x - 6

First: subtract 2x from both sides thus giving you

3 = 3x - 6

Second: add six to both sides, divide by three and simplify

9 = 3x  

[tex]\frac{9}{3}[/tex] = [tex]\frac{3x}{3}[/tex]  

x = 3

Lastly: substitute values of x and simplify

AB = 2(3) + 3 = 9

BD = 5(3) - 6 = 9

9 + 9 = 18

AD = 18
