<span>The 6 playing cards may be arranged into 6 factorial (!) combinations, since the order of the cards does not matter, and since for each card we select, there is now one less card to choose from (for example 6 cards to start, then 5 to choose from, then 4, etc.)
So the number of combinations is 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720 combinations.</span>
Answer:
73.13
Step-by-step explanation:
I think this <em><u>might</u></em><em><u> </u></em>be the right answer.
Answer:
3a – 4b + 6c – 3d
when a = 5 b = 4 c = 3 d = 2
the value
= 3×5 - 4×4 + 6×3 - 3×2
=15-16+18-6
=11
You can factor out a 5n to get
5n(4m-3)
6.4 is the answer hope this helps
