The line is leaning to the left, so the slope is negative, eliminate A and D
when x is 3, y is -2, so C is the correct answer
3x² + 14x + 8
3x² + 12x + 2x + 8
3x(x) + 3x(4) + 2(x) + 2(4)
3x(x + 4) + 2(x + 4)
(3x + 2)(x + 4)

Answer:
421.4 miles
Step-by-step explanation:
The flight legs are orthogonal, so the distance can be found using the Pythagorean theorem:
1.2 h × 120 mph = 144 mi
3.3 h × 120 mph = 396 mi
The distance at the end of the second flight leg is ...
d = √(144² +396²) = √177552 ≈ 421.37
The plane is about 421.4 miles from its starting point.
_____
The heading to its end point is 20° +arctan(3.3/1.2) ≈ 90.02°.
