Answer:
$127.80
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
The area of deltoid is defined by formula:
Where e and f are diagonals.
If you were to double the size of either one. Let's say f. You would result with:
Which means if either of diagonals double in length the area of deltoid will be twice as big as it was before.
Hope this helps.

Answer:
- D. 5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.
Step-by-step explanation:
We are given directions and position change.
This is about the velocity, the speed doesn't take into account the direction.
We also see the change in the velocity. The numbers give us instantaneous velocities and the displacement is the average velocity as the sum of vectors.
Considering the above explanation, correct choice is D.
Answer:
-5x²+13x+6
Step-by-step explanation:
(x-3)*(2x-7x-2)
(x-3)*(-5x-2)
-5x²-2x+15x+6
-5x²+13x+6
