Hi there!
The question is asking us to simplify the expression (x² + 3x - 7)(2x - 5) and write the answer in standard form. Here is how you do that -
Original: (x² + 3x - 7)(2x - 5)
Break it apart - [(x² + 3x - 7)(2x)] + [(x² + 3x - 7)(-5)]
Simplify -
2x³ + 6x² - 14x - 5x² - 15x + 35
Now, combine like terms -
2x³ + x² - 29x + 35
Therefore, the answer to your query is 2x³ + x² - 29x + 35. Hope this helps!

Answer:
D 776 m.
Step-by-step explanation:
Use trigonometry. The line of flight of the plane, it's height above the ground and the distance travelled along the ground form a right angled triangle.
So sin 15 = opposite side / hypotenuse.
sin 15 = h / 3000 where h = its height..
h = 3000 sin 15
= 776 m.
