The answer would be 8.5
Remember the Pythagorean theorem. A^2+ B^2= C^2. The hypotenuse, or 9 (in this question) will always be C
I think that the answer is 2, because if you multiply two by each factor in the original photograph then you get the size of the new photograph.
F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x
Answer: -6x² + 4x
