Answer:
The answer (using BEDMAS) is 27
Step-by-step explanation:
The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS
First solve the smaller bracket
18 + 2 = 20
So then it becomes 9 x [20 ÷ 5 - 1]
Do the division inside the bracket next
20 ÷ 5 = 4
Then it becomes 9 x [4 - 1]
Do then subtraction within the bracket
4 - 1 = 3
Then it becomes 9 x 3
Finally solve 9 x 3 which equals 27
The pentagon does not belong because it has 5 sides while the other 3 shapes have only 4 sides.
<u>Answer-</u>

<u>Solution-</u>
As we know that, on the number line, if a number is on the right of another number, then the former number is greater than the later number.
As, the number on the right side are 4, 5, ...so on (4 is dotted so it is included)
So the inequality will be 
As, the number on the left side are -3, -4, -5, ..... so on (-2 is not dotted so it is excluded)
So the inequality will be 
Then the compound inequality will be,
