Answer 2

Can you show me how you tried solving it?

Answer 3

OH! Sum of the outer and inner products.... so \((11x*7)+(-7*2x)\) :) I hope this helps...

Answer 4

So the answer is 63x?

Answer 5

77x-14x=63x...yes :)

Answer 6

Thanks :)

Answer 7

So yes

"inner product" means \(\large (-7 \times 2x)\)
"outer product is the \(\large (11x \times 7)\)

So yes...sum those up as @haleyelizabeth2017 has shown

\[\large (-7 \times 2x)+(11x \times 7)\]
\[\large -14x + 77x\]
\[\large 63x\]
