Answer.

5.

Solve for x ✓3x^2-2✓2x-2✓3=0

Answer»

Answer:

a = √3 , B = -2√2. , c = -2√3.

x = { - b +/-√(b^2 - 4.a.c) }/2.a

x = { 2√2 +/-√( 8 + 24) }/2.√3

x. = { 2√2 +/- 4√2}/2√3.

or, x = (2√2+4√2)/2√3 , (2√2–4√2)/2√3.

or, x = (6√2)/(2√3) , (-2√2)/(2√3).

or, x = (3√2.√3)/(√3.√3). , (-√2.√3)/(√3.√3).

or, x = √6. , - (√6)/3.

or, x = 2.4494 , -(2.4494)/3.

or, x = 2.4494. , - 0.8131. Answer.

Answer» $\huge\pink{\mid{\fbox{\tt(answer)}\mid}}$ Critical Analysis of The Nightingale and the Glow-worm: In this poem, the poet tells us a STORY with a moral. However, he envisions a very noble role for the poet. He feels that the poet should be responsible for more than just teaching his readers a lesson.

17 = X / 20

x = 17 × 20

x = 340

Thus, sum of observations = 340

when 20 is REPLACED by 40

the sum of observations= 340-20+40=360

47.	How is the lithosphere formed?
Answer» Answer: The solidification of the magma ocean, UPON which the process of the formation of the LITHOSPHERE is dependent, most likely began with the formation of a forsterite (or forsterite-rich peridotite) slab at a depth of about 100 KM FOLLOWED by the solidification of Earth’s surface, cooled by heat radiation from the surface and the cooling effect of the early ATMOSPHERE.

The negatively charged particles are embedded in the positively charged sphere. These negative and POSITIVE charges are equal in magnitude. Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses ONE or more electrons, it becomes an ion.

Answer» Step-by-step explanation: GIVEN :- Ram is 3 years OLDER than Rohan. Six years ago, Ram’s AGE was four times Rohan’s age TO FIND :- ✳ The present age of Rohan. SOLUTION :- Taking, Ram's present age be x years . Rohan's present age be y years. Situation 1. ⭐ Ram is 3 years older than Rohan. ↗ x = y + 3.........(1) Situation 2. ⭐ Six years ago, Ram’s age was four times Rohan’s age Ram's age = (x–6) years. Rohan's age = (y–6) years. According to the question, ⭐ (x−6) = 4 (y−6) ⟶ x − 6 = 4y − 24 ⟶ x − 4y = − 24 + 6 ⟶ x − 4y = −18.....(2) Putting From 1.in 2 , ⟶ (y + 3) − 4y = − 18 ⟶ − 3y + 3 = − 18 ⟶ − 3y = − 18 − 3 ⟶ −3y = −21 ⟶ y= −21/-3 ⟶ y = 21/3 ⟶ y = 7 Putting y in 1 , ▶ x = y + 3 ▶ x = 7 + 3 ▶ x = 10 ➡ Ram is 10 years OLD & Rohan is 7 year old.

Q49. Ram is 3 years older than Thoiba. If theage of Ram is 4 times the age of Thoiba fouryears ago, the present age of Ram is

Answer»

Step-by-step explanation:

GIVEN :-

Ram is 3 years OLDER than Rohan.

Six years ago, Ram’s AGE was four times Rohan’s age

TO FIND :-

✳ The present age of Rohan.

SOLUTION :-

Taking,

Ram's present age be x years .

Rohan's present age be y years.

Situation 1.

⭐ Ram is 3 years older than Rohan.

↗ x = y + 3.........(1)

Situation 2.

⭐ Six years ago, Ram’s age was four times Rohan’s age

Ram's age = (x–6) years.

Rohan's age = (y–6) years.

According to the question,

⭐ (x−6) = 4 (y−6)

⟶ x − 6 = 4y − 24

⟶ x − 4y = − 24 + 6

⟶ x − 4y = −18.....(2)

Putting From 1.in 2 ,

⟶ (y + 3) − 4y = − 18

⟶ − 3y + 3 = − 18

⟶ − 3y = − 18 − 3

⟶ −3y = −21

⟶ y= −21/-3

⟶ y = 21/3

⟶ y = 7

Putting y in 1 ,

▶ x = y + 3

▶ x = 7 + 3

▶ x = 10

➡ Ram is 10 years OLD & Rohan is 7 year old.
