Answer:

a>-40

Step-by-step explanation:

[tex]4 + 2(a + 5) < - 2 - a - 4 \\ 4 + 20 + 10 < - 2 - a - 4 \\ 34 < - 2 - a - 4 \\ 34 + 2 < - 2 - a + 4 + 2[/tex]

[tex]36 < - a - 4 \\ 36 + 4 < - a - 4 + 4 \\ 40 < - a \\ \frac{40}{ - 1} < \frac{ - a}{ - 1} [/tex]

[tex]a > 40[/tex]

  1. Step1 : Use 2 to open the bracket
  2. Add 4+10+20
  3. Subtract +2 from both sides
  4. Add + 4 to both sides
  5. Divide both sides by -1 and flip the sign.
