Answer:
Step-by-step explanation:
A)
d = r* t Divide both sides by t
d/t = r
r = d/ t
B)
d = 800000
t = 4 hours
r = 800000 / 4
r = 200000 meters/hour
C
r = 200000 meters / hour * [ 1 km / 1000 meters]
r = 200 km / hr
D
I imagine you are more familiar (especially if you live anywhere but the states) with 200 km/ hour. I am very doubtful that any bird can keep that up for 4 hours. 200 km / hour is equal to about 125 miles / hour. There are few places that will allow a car to travel at that speed. You should be using km/hour because you (should) be more familiar with the units.
Im going to assume that 3√ is √3
And √3 is irrational because You cant square root it without getting nuked with a Random Number generator of decimals.
The polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

What is square?</h3>
The square can be defined as a two-dimensional figure that has 4 equal sides.
Given are the equations of the areas of the polynomial.
Option C: 
We can write the above equation as,
Here a = 4x and b = 3, so
The simplification of the area of a polynomial is (4x+3)^2 which represents the area of a square.
Hence the polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

Answer:
Step-by-step explanation:
x = 2 is a vertical line; all values of y are possible.
y ≤ -3 is a region which includes -3 and all numbers less than -3.
So: draw a light line x = 2. Then draw a dark line at y = -3. Now darken the line x = 2 for (-infinity, -3].
