Your answer would be 2b+9!
Answer:
Actual speed = 288 miles per hour
Actual direction angle = 
Step-by-step explanation:
"Bearing" is the relative position of an object outside the plane compared to the position of the plane.
Heading the the direction the nose of the plane is pointing.
Course is the direction that pilot wants the plane to go.
Wind direction is always the direction the wind is blowing from.
The airplane is traveling at a speed of 240 miles/hour with a bearing of 110°.
If the plane is traveling with a bearing of 110° and the wind is blown at a bearing of 325°.


The Ground speed will be in excess of the airspeed and true direction will be south if the indicated heading.
The tailwind component is:

And the cross wind component is:
And that is,


So the actual speed of the plane is 288 miles per hour.
The deviation in the direction is:
Let the direction angle be 'x'.

So the actual direction angle is
.
Answer:
The answer to your question is below
Step-by-step explanation:
Side 1: 3x² - 2x - 1
Side 2: 9x + 2x² - 3
Perimeter: 5x³ + 4x² - x - 3
a) Length of side 1 and side 2
Length = (3x² - 2x - 1) + (9x + 2x² - 3)
= 3x² - 2x - 1 + 9x + 2x² - 3
= (3x² + 2x²) + (-2x + 9x) + (-1 - 3)
= 5x² + 7x - 4
b) Length of the third side
Third side = Perimeter - side 1 - side 2
Third side = 5x³ + 4x² - x - 3 - (5x² + 7x - 4)
Third side = 5x³ + 4x² - x - 3 - 5x² - 7x + 4
Third side = 5x³ + (4x² - 5x²) + (-x - 7x) + (-3 + 4)
Third side = 5x³ - x² - 8x + 1
c) Yes, in this problem we did both operations (addition and subtraction) and we can notice that the polynomials are closed. Also they follow the closure property the addition or subtraction of two polynomials gives another polynomial.
