The airplane's speed in the direction of its heading is
.. 410 mph +r*cos(θ)
where θ is the angle between the plane's heading and the direction the wind is moving toward.
That is, if the plane is moving "with the wind," its speed is (410 +r) mph.
If the plane is moving "against the wind", its speed is (410 -r) mph.
Answer: Choice B) The expression (10-2x)(30-2x)x represents the volume of the box
----------------------------------------------------
----------------------------------------------------
The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x
Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter).
The height of the box is x inches due to this portion being folded up.
Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x
Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).
8-5=3
3-5=-2
-2-5=-7
So the rule is -5 or subtract 5

Step-by-step explanation:
The median joins the midpoints of AD and CB. It's formula is 1/2 * (5 + 15) = 10 for its length.
