Answer 1

The final inequality expression is : -2 < x < 18 and the final range is -2 and 18

From the expression given ;

• 0 < 2x + 4 < 40

To solve , subtract 4 from all sides to isolate 2x;

0 - 4 < 2x + 4 - 4 < 40 - 4

-4 < 2x < 36

divide through by 2x to isolate x

-4/2 < 2x/2 < 36/2

-2 < x < 18

Therefore, the final inequality expression is : -2 < x < 18 and the final range is -2 and 18
