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:
X=5
Step-by-step explanation:
(step 1) 2 - 3x = -x - 8
-3x + 2 = -x -8
(step 2)
-3x + 2 = -x - 8
-3 + 2 - 2 = -x -8 -2
(step 3)
-3x = -x- 10
(step 4)
-3 + x = -x -10 +x
(step 5)
-2x = -10
Answer
x = 5
Answer:
9x+4y+2
Step-by-step explanation:
3x^2+4y+2
3x^2 = 3x*3= 9x
9x+4y+2
So the answer is 9x+4y+2
Answer:
9/16
Step-by-step explanation:
3/8 ÷ 2/3
Copy dot flip
3/8 * 3/2
Multiply the numerators
3*3=9
Multiply the denominators
8*2 = 16
Numerator over denominator
9/16
The answer is 37 because 6 times 5 is 30 then plus 7 is 37
