The gcf is 8
That is the answer
Answer:
Step-by-step explanation:
Let us first find the number of possible credit card numbers that can be formed with the numbers 0 - 9.
We want to form a 16 digit number out of 10 digits, so, we have:
There are numbers that can be formed.
There are only 100 million valid numbers (). Let the number of valid numbers be n.
Therefore, the probability of picking a number that is valid is:
P(valid) = n / N
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 54 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 54 is 100%, so we can write it down as 54=100%.
4. We know, that x is 2.9% of the output value, so we can write it down as x=2.9%.
5. Now we have two simple equations:
1) 54=100%
2) x=2.9%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
54/x=100%/2.9%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 2.9% of 54
54/x=100/2.9
(54/x)*x=(100/2.9)*x - we multiply both sides of the equation by x
54=34.48275862069*x - we divide both sides of the equation by (34.48275862069) to get x
54/34.48275862069=x
1.566=x
x=1.566
now we have:
2.9% of 54=1.566
Answer:
2x (2x^2 +x +1)
Step-by-step explanation:
f(x)-g(x)
9x^3 + 2x^2 -5x + 4 - (5x^3 -7x +4)
9x^3 + 2x^2 -5x + 4 - 5x^3 +7x -4
4x^3 +2x^2 +2x
2x (2x^2 +x +1)
