How does the diagram show that x + 4 has the same value as 17

Step-by-step explanation:
We can tell that x + 4 has the value of 17 by visualization.
[tex]\boxed{ \: \: \: \: \: \: x \: \: \: \: \: \: }\boxed{4}[/tex]
x is larger in length, we can identify that x has the value of 13 when 17 and 4 subtract.
