I might need simple and explanatory answers tho these questions- if youre able to help, thank you!

Step-by-step (with answer) explanation:

2. You put 15x in the first part and 10 in the second part. Answer is 15x + 10.

You are pretty much multiplying 5 times 3x in the first part of the box and 5 times 2 in the second part of the box.

3. 7x in the first part of the box and -63 in the second part of the box. Ans. 7x - 63.

4. 30x + 45

You are just doing 5 times 6x and 5 times 9 since 5 is outside the parentheses and 6x and 9 are inside it.

5. 12k - 8

6. 9t + 3

7. 4 - 3j

8.   8p + 56 + 16q

9. 12.8d - 40

10. 24c - 2

Negative 12 (from 6 times 2) and positive 10 are added together to make 2 (since it says to combine any like terms.

11. 23b + 42

18b and 5b are added together since they are like terms.

12. 11x + 14

3x and 8x are added together since they are like terms (which makes 11x).

Hope you like :)
