Answer:

C

Step-by-step explanation:

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!
