Answer:
A
Step-by-step explanation:
Given
(- 12x + 4) +
(6x + 8) ← distribute parenthesis
= - 9x + 3 + 3x + 4 ← collect like terms
= - 6x + 7 → A
7 > z + 18 ≥ 6
Subtract 18 from all 3 parts:
7-18 > z +18 -18 ≥ 6-18
-11 > z ≥ -12
Start with

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

Subtract 3 from both sides:

we know that
in expanded form is equal to

therefore
<u>the answer is</u>
