Answer:

Step-by-step explanation:
We will solve the given expressions and find the answer in decimals.
1).
= 
= 5.4 - 2.8
= 2.6
2). 
= -3.3 + 0.35
= -2.95
3).
= -3.125
4). (-4.5) × (-2.3) = 10.35
Solution of the expressions in the increasing order will be,
-3.125 < -2.95 < 2.6 < 10.35

From the research I just did, it seems that 6 lines will be drawn when constructing an inscribed square.
Hope this helped :)
Answer:
88
Step-by-step explanation:
The original number ⇒ 100
100 is increased by 10%
The result is 20% reduced.
Calculate increase.
100 × (1 + 10%)
100 × (1.1)
= 110
Calculate decrease.
110 × (1 - 20%)
110 × 0.8
= 88
