I answered this question just now! Did you add another question like this?
1. rule = r - 12 (number = 25)
2. rule = a + 34 (number = 43)
3. rule = s - 5 (number = 20)
4. rule = b + 16 (number = 32)
5. rule = w + 3 (number = 9)
6. rule = n + 9 (number = 42)
7. 15 - n when n = 9 would be 15 - 9, and your answer would be 6.
8. "32 more than a number d" implies add d to 32, so your answer is C. 32 + d
8 ) 712
8 goes into 71 8 times; the product of 8 and 8 is 64.
Subtracting this 64 from 71, we get 7, to which we append 2: 8 ) 72.
8 divides evenly into 72: 9.
Thus, the desired quotient is 89.
Answer :

step-by-step explanation :

This can be rewritten as:

Now,

The law of indices states that:

It implies that, when dividing two expressions with the same bases, repeat one of the bases and subtract the exponents.
Therefore,


Note: Any non-zero number exponent zero is 1
Also

Hence:
