I see the worksheet you uploaded focuses on simplifying algebraic expressions. Let's work through the simplification of a few problems to illustrate the process, and then I can assist with any specific questions you might have.

Here are the steps for the first few:

1. Problem 11: $4p + 8p + 10$

   • Combine like terms: $4p + 8p = 12p$.
   • Answer: $12p + 10$.

2. Problem 12: $12 + 2x - 14x + 8$

   • Combine like terms for $x$: $2x - 14x = -12x$.
   • Combine constants: $12 + 8 = 20$.
   • Answer: $-12x + 20$.

3. Problem 13: $a - 7 - 4a + 2$

   • Combine like terms for $a$: $a - 4a = -3a$.
   • Combine constants: $-7 + 2 = -5$.
   • Answer: $-3a - 5$.

4. Problem 14: $r - 2s + 2r - 8s$

   • Combine like terms for $r$: $r + 2r = 3r$.
   • Combine like terms for $s$: $-2s - 8s = -10s$.
   • Answer: $3r - 10s$.

5. Problem 15: $x + 4x + 4 - 8x$

   • Combine like terms for $x$: $x + 4x - 8x = -3x$.
   • Constant term remains $+4$.
   • Answer: $-3x + 4$.
