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

Pls help me factorize.Thanks!

We can change the sign of the second term, so that the two parenthesis are the same:

$6(a-1)b^3+3(1-a)b^2 = 6(a-1)b^3-3(a-1)b^2$

Now, both terms have in common a 3, becase the numeric factors are 3 and 6. If we factor the 3, we have

$6(a-1)b^3-3(a-1)b^2 = 3(2(a-1)b^3-(a-1)b^2)$

The parenthesis (a-1) is also in common, so we can factor it as well:

$3(2(a-1)b^3-(a-1)b^2) = 3(a-1)(2b^3-b^2)$

Finally, both terms in the parenthesis contain $b^2$ , because it's the power of b with the lowest exponent:

$3(a-1)(2b^3-b^2) =3(a-1)b^2(2b-1)$

So, the factorization is

$3b^2(a-1)(2b-1)$

You can swap the order of the four factors (3, b^2, a-1 and 2b-1) as you like: the multiplication is commutative.
