Answer:
1) Simplification:
8x^2 - 5x - 7 - (9x^2 - 3x - 5) + (x + 7)(x +1) =
8x^2 - 5x - 7 - 9x^2 + 3x + 5 + x^2 + 8x + 7 =
6x + 5
2) That is a linear polynomial.
The degree is 1.

B is the answer i just took the oddyseyware lesson and got 100%
it answer is 3 because it is trigonometry
$120
80%=$96
1%=80%/80=96/80=1.2
100%=1%×100%=1.2×100=120
