Answer: 40 and 52
Step-by-step explanation:
, so both 40 and 52 have a factor of 4.
Make 3.0035 into a proportion, or over 1000000, to make it a whole number. 30035/1000000.
<span>Say the code only needed to be one number long. Going from 0-9, there are ten digits. Therefore, there are ten unique codes.
Now say the code has to be two numbers long. There are ten possibilities
for the first digit, 0-9. But the second digit only has nine
possibilities, since each number has to be different. (The first number
might be 0, so the second can only go from 1-9) For each of the first
ten possibilities, there are nine possibilities for the second. We
multiply those two numbers together, 10 * 9, and we get 90.
Now we just extend the logic. The third number only has eight
possibilities, while the fourth number only has seven. 10 * 9 * 8 * 7 =
5040 possible codes. I hope this helped! has a great day! :)</span>
Answer: x=1 my friend
Step-by-step explanation:
Answer:
Width = 15 inches Length = 20 inches
Step-by-step explanation:
The area of a rectangle is calculated using the following formula.
(1)
Where L is the length and x is the width of the rectangle
In this case we know that the length of the rectangle is 5 inches greater than its width. This means that:
(2)
Also The area of a rectangle can be represented by the equation 
so to find the width x we solve the equation
(3)
For an equation of the form 
the quadratic formula is:
In this case note that:
Then:
→ 
→ 
We take the positive solution 
Now we use equation (2) to find L
