Consider
× 
=

Thus and are in proportion
This does not happen for any of the other three.
Answer:
Step-by-step explanation:
Let f(x) = 3x² - x³ - 3x + 5 and g(x) = x - 1 - x²
-x² + x - 1) -x³ + 3x² - 3x + 5(x - 2
-x³ + x² - x
-------------------------
2x² - 2x + 5
2x² - 2x + 2

Answer:
x = 25
Step-by-step explanation:
The interior angle adjacent to the 123° angle is supplementary to it.
Its measure is 180° - 123° = 57°
The sum of the measures of the interior angles of a polygon is
(n - 2)180° = (4 - 2)180° = 2(180°) = 360°
3x + 7 + 96 + 5x + 57 = 360
8x + 160 = 360
8x = 200
x = 25
