Answer:
D
Step-by-step explanation:
There are 9 letters, which contains 2Qs, 3Ls and 4Bs.
If the 9 letters are distinct, the number of permutations they have will be 9!.
! is the factorial sign.
9! = 9*8*7*6*5*4*3*2*1
HOWEVER, we have some identical elements, so we need to get rid of the permutations of the same letters.
Thus we have:
The answer is D
Answer:
The correct answer is 6.
Step-by-step explanation:
2x2 – 2x + 10 <------ This is the original expression.
2x2 – 2(4) + 10 <----- Change the variable.
4 - 2(4) + 10 <------- Do the multiplication to the left.
4 - 8 + 10 = <------ Do the multiplication in the middle.
-4 + 10 = <----- Do the subtraction to the left.
6 <----- Simplify
Hope this helps! :D
All you have to do is multiply them all.
3*3*4*2=72
