Answer:

no solution

Step-by-step explanation:

sqrt(3x+1) +7 = 5

Subtract 7 from each side

sqrt(3x+1) +7 -7= 5-7

sqrt(3x+1)  = -2

The sqrt cannot be negative so there is no solution

Sophie [7]

Answer:

11. 9hrs

12. 5hrs 35min

12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min

13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min

Question
RideAnS [48]

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:

\dfrac{9!}{2!*3!*4!} =\dfrac{9*8*7*6*5}{2*3*2*1} = \dfrac{9*4*7*5}{1} = 63*20=1260

The answer is D
