Answer:

E. 12

Step-by-step explanation:

1. p÷q=3. p+q=8 We know that p and q are positive, as dividing by a negative number gives a negative product.

2. 4÷4 does not equal to 3, so neither p nor q can equal 4.

3. As 6÷2=3, p=6 and q=2, or it could be the other way around.

4. Since p=6 and q=2, 6x2=12.

5. pq=12.

Hope the explanation helps you!
