Correct option is A) is

B) My / surname 

Correct option is C) I am 

C) Her / She’s 

A) is / He’s 

Solution: We have

2/x²-5/x+2=0

=>(2-5x+2x²)/x²=0

=>2x²-5x+2=0

=>2x²-4x-x+2=0

=>2x(x-2)-1(x-2)=0

=>2x-1=0 or x-2=0

=>x=1/2 or x=2

Already there are 5 peoples in the room.
Now,
After you enter into the room, the total number of persons will be
5 + 1 = 6
Then, you killed 4, so the number of persons alive in the room is 2.

But it is asked to find out the total number of persons regardless of alive or dead.

Hence, the 6 persons will remain inside the room.

Originally it is mentioned that there were 5 people in room and as the killer or I come, It makes 6 people in the room.

So after killing 4 people, no. of people left in the room will be 6, 4 dead and 2 alive.

Answer: 6 persons.

Explanation: 

If there are 5 people in a room, and one walks into the room and kill 4 out of 5 persons, then there will be 6 persons in the room because the person who killed will also be counted as a person in the room, along with those who the person killed. The ones who were killed would not change into anything else or disappear from that room if the one person who killed them has entered the room. So, including that one, there will be 6 persons in that room.

Concept: 

• Every region has a different house.
• The type of house depends on the climatic conditions in the region. 
• Houses are built specially to suit the needs of the people.​

Explanation:

Igloo:

• The Eskimos make their houses out of ice called an igloo.
• Since the air between the ice walls prevents the inside heat from escaping.
• Snow is believed to be a good insulator of heat and traps it.
• Igloos are temporary winter homes mainly found in Canada.
• Eskimos are the people living in the Arctic and subarctic regions of the US, Russia, Canada, and Greenland.
• In India, tourists can experience igloos in Manali in the winter season.

Thus, the house made of snow is known as Igloo.

Rain Basera:

• Rain Basera or common shelter (sometimes called as the Night shelter) is a place created by the Government or NGOs for the homeless.
• It is a place where the homeless find shelter.

Green house:

• A greenhouse looks like a small glasshouse and is used for growing plants, especially during winter.
• In a greenhouse, the glass panel lets the light in but does not allow heat to escape.
• Therefore, the greenhouse warms up, very much like inside a car that has been parked in the sun for a few hours. 
• The term ‘Greenhouse effect’ has been derived from a phenomenon that occurs in a greenhouse.

Living standard means the level of living of people at which they live. If they live in hygienic conditions enjoying all the comforts of life, it means their living standard is high. On the contrary, if they are bound to live in a filthy surroundings and drink polluted water and eat unhygienic foods, it means they lead a low standard of living. Public health. It refers to the health of the general public.

Ionization energy :The energy required to remove an electron from the outermost orbit or shell of a neutral gaseous atom is called ionization energy. Ionization energy of an element depends on its : 

(1) Nuclear charge : More the nuclear charge, more is the ionization energy. 

Ex : Between ₁₁Na and ₁₇Cl, chlorine atom has more ionization energy. 

(2) Screening effect or shielding effect :The shells with electrons between nucleus and the valence shell, act as screens and decrease nuclear attraction over valence electron. This is called the screening effect. More the screening effect, less is the ionization energy. 

Ex : Between ₃Li and ₅₅Cs, the element ₅₅Cs with more inner shells has less ionization energy. 

(3) Penetration power of the orbitals :Orbitals belonging to the same main shell have different piercing power towards the nucleus.

Ex : 4s > 4p > 4d > 4f > in the the penetration. 

It is easier to get 4f electron than 4s. 

Between ₄Be (1s² 2s²) and ₅B (1s² 2s² 2p¹ ) the element ₅B has less ionization energy due to less penetration power of 2p compared to 2s. 

(4) Stable configuration : It is easier to remove one electron from ₈O (1s² 2s² sp⁴ ) than ₇N (1s² 2s² 2p³ ). This is because ₇N has stable half filled configuration. 

(5) Atomic radius : As atomic radius increases, the ionization energy decreases. 

Ex : I.E. of F is greater than that of I, because the atomic radius of I is more than F.

(a) The modern periodic table is arranged in groups and periods based on the electronic configuration of the atoms of elements. 

(b) Physical and chemical properties of elements are related to their electronic configurations particularly the outershell configurations. 

(c) The atoms of the elements in a group possess similar electronic configurations. 

(d) The elements in a group should have similar chemical properties and there should be regular gradation in their physical properties from top to bottom. 

(e) Across the table from left to right in any period, elements get an increase in the atomic number by 1 unit between any two successive elements. 

(f) Therefore the electronic configuration of valence shell of any two elements in a given period is not same. 

(g) Due to this reason elements along a period possess different chemical properties with regular gradation in their physical properties from left to right.
