**Answer:**

**b. {-9, 3}.**

**Step-by-step explanation:**

x^2 + 6x - 27 = 0

We need 2 numbers whose product is -27 and whose sum is + 6.

These are + 9 and - 3. So the factors are:

(x - 3)(x + 9) = 0

(x - 3) = 0 or (x + 9) = 0

x = 3 or -9.

Answer:28 bags with 17 cents left over

Step-by-step explanation: First, subtract the amount of 37.85 from what he started out with, 52.02. You should get 14.17.

Then, if we have 14 whole dollars and the bags each cost 50 cents, then we can just multiply 14 by 2, since each dollar equals 50 cents times 2.

EX: $1=50 cents x2. So 14 dollars x2 would be like saying the first amount 50 cents doubled. You should get 28 bags, with 17 cents left over :). Let me know if this makes sense! I really hope this helps you.
