Answer:
675
Step-by-step explanation:
This is going to be really hard for you to understand unless you know factorials.
The first four letters is a combination out of 6 letters; we call it 6 choose 4. As you may know, factorial is the multiplication of a number and it's previous digits. For example, 3! = 1 x 2 x 3
The 6 choose 4 is (6!/4!2!) = (5x6)/2 = 15
The 10 choose 2 is (10!/2!8!) = (9x10)/2 = 45
Then you multiply both as they're independent:
15 x 45 = 675 serial numbers
RESULT is 10,496.77 I think
Answer: 28
Step-by-step explanation:
2.124 + x + y + z + w = 360
x = y
z = w
2x + 2z = 360 - 248
2x + 2z = 112
x + z = 56
x = z
x = y
y = 28
I hope I helped you.
