pls help meeeeee i dont wanna fail thissssss

Answer:
A. [tex]12^{2} -11^{2} =a^{2}[/tex]
Step-by-step explanation:
This equation CAN NOT be used to find the value of a since the numbers aren't correctly placed.
[tex]12^{2}[/tex] = [tex]c^{2}[/tex]
[tex]11^{2}[/tex] = [tex]b^{2}[/tex]
[tex]a^{2} = a^{2}[/tex]
Once you've input these in the correct places, your equation should be:
[tex]a^{2} +11^{2} =12^{2}[/tex]
Hope this helps!
