5-2n....
_ _ _ _......_

Answer 1

For the first question you multiply 4 by 2x and then -1, getting 8x - 4. 3 multiply by 2x and then +5 gives you 6x + 15. 8x +6x = 14x; -4 + 15 = 11. The answer to the first question would be 14x + 11.

For the second question:
1. 3
2. 1
3. -1
4. -3
The tenth term. -15

Answer 2

4(2x - 1) + 3(2x + 5)
8x - 4 + 6x + 15
14x + 11 (the answer).

3, 1, -1, -3, -15 (the 10th term)
