40 km - meters is 40 * 1000 whch is 40000 meters per hour
Answer: a) w = -26, -2
b) x = -4, -1
c) k = 17, -1
d) z = 65, 935
Multiple choice: D)
Step-by-step explanation:
a) (w+26)(w+2) = 0
w = -26, w = -2
b) (x+4)(x+1) = 0
x = -4, x = -1
c) (k-17)(k+1) = 0
k = 17, k = -1
d) (z-65)(z-935) = 0
z = 65, x z 935
Multiple Choice
D)
Multiply all terms by 2.

Answer:
754.2
Step-by-step explanation:
First of all, we cannot solve the question the way it is. We need to make 0.1 into a whole number. If we move the decimal to the right, once, then it will become the number one.
Of course, what we do to one, we have to do to the other. We move the decimal to 75.42 to the right one. Now it is 754.2
That looks like the answer. The reason is because we are now dividing by one. Something divided by one, will always be itself.
Now we have the answer of 754.2.
For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

Where "r" represents the radius of the circle, in this case 
Substituting in the perimeter equation we have:

Rationalizing we have:

Taking out common factor
