I need answers and explanation for only A not B

Answer:
See attachment
Step-by-step explanation:
The given inequality is [tex]13\:<\:x+11[/tex]
We subtract 11 from both sides of the equation to get:
[tex]13-11\:<\:x+11-11[/tex]
This simplifies to:
[tex]2\:<\:x[/tex]
We can rewrite this as:
[tex]x\:>\:2[/tex]
We graph this by drawing an open circle at two and direct the arrow to the right as shown in the attachment.
