Answer:
3
-3
sqrt(9)
-sqrt(9)
Step-by-step explanation:
What number multiplied by itself will give you 9
3*3 =9
-3*-3 =9
sqrt(9) * sqrt(9) = sqrt(81) = 9
-sqrt(9) * -sqrt(9) = + sqrt(81) =9

Step-by-step explanation:
Solution
The sequence is an Arithmetic sequence.
Here the 1st term = -13
An = A(n-1) + 4
Therefore, the common difference (d) = 4
2nd term = first term + common difference
2nd term = -13 + 4 = -9
The answer is -9.
Answer:
1/13
Step-by-step explanation:
There are 4 nines in a deck so the probability is 4/52 = 1/13
