You have to pick at least one even factor from the set to make an even product.
There are 3 even numbers to choose from, and we can pick up to 3 additional odd numbers.
For example, if we pick out 1 even number and 2 odd numbers, this can be done in
ways. If we pick out 3 even numbers and 0 odd numbers, this can be done in
way.
The total count is then the sum of all possible selections with at least 1 even number and between 0 and 3 odd numbers.

Answer:
2. the final answer is -36n+3
3. the final answer is -4x-10
4. the final answer is 3c-81
5. the final answer is 17b-31
6. the final answer is 56y+64
7. the final answer is 24q+30
Note: I simplify each problem
7-5.5=1.5
so each drop leaf is 1.5
2×1.5=3
so 7 when both drop leafs are up
7-3=4
There's your answer
