Choose the missing step in the given solution to the inequality −x − 10 > 14 + 2x. −x − 10 > 14 + 2x −3x − 10 > 14 x < −8 −3x > 24 −3x > 4 −3x > −4 −3x < 24

  −3x > 24

Step-by-step explanation:

Adding 10 to both sides of the inequality will give the missing step:

  -3x -10 +10 > 14 +10

  -3x > 24

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
