• Sole proprietorship firm has limitations of unlimited responsibility on the proprietor, difficult to raise more capital, invest in buying large space and doing business at a larger scale. These limitations limit the span of the business.
• On the other hand, with time trade and commerce got bigger and bigger.
• To divide the responsibilities, avail more capital, skills, administrative powers and risk bearing capacity, establish business at a large scale and overcome the limitations of sole proprietorship, came the concept of partnership where in more than one person owns and manages the firm.

The ornamental plants are called ferns.

Radius of each circle = a meter 

If we join the centre of each circle it makes a square of side = 2a

 Area of square = (2a)² = 4a² m² 

Area of each quadrant of circle = \(\frac{πr^2}4\) = \(\frac{πa^2}4\) m²

Area of 4 quadrants = \(4\times\frac{πa^2}4\) = πa² m²

So, 

Area between circles = 4a² – πa² 

= \(4a^2 - \frac{22}7a^2\) = \(\frac{28a^2 - 22a^2}7\) = \(\frac{6a^2}7\) m²

(d) 7/3

Explanation:

Given 2y+(5/3)=(26/3)-y

On rearranging, 2y+y=(26-5)/3

3y=7

y=7/3

3x = 2x + 18

On transposing 2x to L.H.S, we obtain

3x − 2x = 18

x = 18

L.H.S = 3x = 3 × 18 = 54

R.H.S = 2x + 18 = 2 × 18 + 18 = 36 + 18 = 54

L.H.S. = R.H.S.

Hence, the result obtained above is correct.

5t - 3 = 3t - 5

On transposing 3t to L.H.S and −3 to R.H.S, we obtain 5t − 3t = −5 − (−3)

2t = −2

On dividing both sides by 2, we obtain

t = −1

L.H.S = 5t − 3 = 5 × (−1) − 3 = −8

R.H.S = 3t − 5 = 3 × (−1) − 5 = − 3 − 5 = −8

L.H.S. = R.H.S.

Hence, the result obtained above is correct.

(b) -1

Explanation:

By transposition 5t-3t=-5+3

2t=-2

t=-1

3y + 4/2 - 6y = -2/5

On multiplying both sides by 5(2 − 6y), we obtain

5( 3y + 4 ) = -2( 2 - 6y )

⇒ 15y + 20 = -4 + 12y

⇒ 15y - 12y = -4 - 20

⇒ 3y = -24

⇒ y = -8

(3t - 2)/4 - (2t + 3)/3 = 2/3 - t

L.C.M. of the denominators, 3 and 4, is 12.

Multiplying both sides by 12, we obtain

3(3t − 2) − 4(2t + 3) = 8 − 12t

⇒ 9t − 6 − 8t − 12 = 8 − 12t (Opening the brackets)

⇒ 9t − 8t + 12t = 8 + 6 + 12

⇒ 13t = 26

⇒ t = 26/13

⇒ t = 2

We have,

2r (y – x) + s (x – y)

= -2r (x – y) + s (x – y)

= (x – y) (-2r + s)

= (x – y) (s – 2r)

z/(z + 15) = 4/9

On multiplying both sides by 9(z + 15), we obtain

9z = 4(z + 15)

⇒ 9z = 4z + 60

⇒ 9z − 4z = 60

⇒ 5z = 60

⇒ z = 12

8x - 3/3x = 2

On multiplying both sides by 3x, we obtain

8x − 3 = 6x

⇒ 8x − 6x = 3

⇒ 2x = 3

⇒ x = 3/2

We have,

7a(2x – 3) + 3b (2x – 3)

= (7a + 3b) (2x – 3)

We know, a³ + b³ + c³ – 3abc = (a + b + c ) (a² + b² + c² – ab – bc − ca) 

Put a + b + c =0 

This implies a³ + b³ + c³ = 3abc

x² – 1 – 2a – a² 

= x² – (1 + 2a + a² ) 

= x² – (a + 1)² 

= (x – (a + 1)(x + (a + 1) 

= (x – a – 1)(x + a + 1)

(i) 17 – 2x + 7x²

Coefficient of x² = 7 

(ii) 9 – 12x + x³ 

Coefficient of x² =0 

(iii)  \(\frac{\pi}{6} x^2 - 3x + 4\) 

Coefficient of x² = \(\frac{\pi}{6}\) 

(iv) √3x – 7 

Coefficient of x² = 0

x - 5/3 = x - 3/5

L.C.M. of the denominators, 3 and 5, is 15.

Multiplying both sides by 15, we obtain

5( x- 5 ) = 3z9 x- 3 )

⇒ 5x − 25 = 3x − 9 (Opening the brackets)

⇒ 5x − 3x = 25 − 9

⇒ 2x = 16

⇒ x = 16/2

⇒ x = 8

(i) 3x² – 4x + 15 

It is a polynomial of x. 

(ii) y² + 2√3 

It is a polynomial of y. 

(iii) 3√x + √2x 

It is not a polynomial since the exponent of 3√x is a rational term. 

(iv) \(x - \frac{4}{x}\)

It is not a polynomial since the exponent of \(\frac{-4}{x}\) is not a positive term. 

(v) x¹² + y³ + t⁵⁰ 

It is a three variable polynomial, x, y and t.

x⁴ + x² + 25 

= (x²)² + 5² + x²     [a² + b² = (a + b)² – 2ab]

= (x² + 5)² −2(x²) (5) + x² 

= (x² + 5) ² −10x² + x² 

= (x² + 5)² − 9x² 

= (x² + 5)² − (3x)²    [a² – b² = (a + b)(a – b ] 

= (x² + 3x + 5)(x² − 3x + 5)

0.25( 4f - 3 ) = 0.05( 10f - 9 )

1/4( 4f - 3 ) = 1/20( 10f - 9 )

5(4f − 3) = 10f − 9

⇒ 20f − 15 = 10f − 9 (Opening the brackets)

⇒ 20f − 10f = − 9 + 15

⇒ 10f = 6

⇒ f = 3/5 = 0.6
