Answer 7

=51

Answer 8

when i did the problem i got 51 then i sq and got 7.14 and its not an anser so i think i messed up some were

Answer 9

\[a^{2}+6^{2}-b^{2}\]
putting values
\[8^{2}+6^{2}-7^{2}\]
\[64+36-49\]
=
\[\sqrt {}\]

Answer 10

=sqrt (51)

Answer 11

what's the final answer given as?

Answer 12

=8^2+6^2-7^2
=64+36-49
=651
take sq root of it
=25.51
25.51 is the answer
