6.	Factorise completely
Answer» ong>ANSWER: $( {(xy)}^{2} + {z}^{2} )(xy + z)(xy - z)$ Step-by-step explanation: *Given* *QUESTION, To factorise, ${(xy)}^{4} - {z}^{4}$ Solution: ${(xy)}^{4} - {z}^{4}$ $= {({(xy)}^{2}) }^{2} - {( {z}^{2} )}^{2}$ Since, ${a}^{2} - {b}^{2} = (a + b)(a - b)$ Hence, $( {(xy)}^{2} + {z}^{2} )( {(xy)}^{2} - {z}^{2} )$ $( {(xy)}^{2} + {z}^{2} )( {(xy)}^{2} - {(z)}^{2} )$ Since, ${a}^{2} - {b}^{2} = (a + b)(a - b)$ Hence, $( {(xy)}^{2} + {z}^{2} )(xy + z)(xy - z)$ RESULT: Hence, the* *REQUIRED* *factorise* *form* is, $( {(xy)}^{2} + {z}^{2} )(xy + z)(xy - z)(ans)$

6.

Factorise completely

Answer»

ong>ANSWER:

$( {(xy)}^{2} + {z}^{2} )(xy + z)(xy - z)$

Step-by-step explanation:

Given QUESTION,

To factorise,

${(xy)}^{4} - {z}^{4}$

Solution:

${(xy)}^{4} - {z}^{4}$

$= {({(xy)}^{2}) }^{2} - {( {z}^{2} )}^{2}$

Since,

${a}^{2} - {b}^{2} = (a + b)(a - b)$

Hence,

$( {(xy)}^{2} + {z}^{2} )( {(xy)}^{2} - {z}^{2} )$

$( {(xy)}^{2} + {z}^{2} )( {(xy)}^{2} - {(z)}^{2} )$

Since,

${a}^{2} - {b}^{2} = (a + b)(a - b)$

Hence,

$( {(xy)}^{2} + {z}^{2} )(xy + z)(xy - z)$

RESULT:

Hence, the REQUIRED factorise form is,

$( {(xy)}^{2} + {z}^{2} )(xy + z)(xy - z)(ans)$

Now, the question has asked us to find out the length of those sides. So, to find the length of those sides, assume the adjacent sides as 1x and 3x. And after that by applying the formula of PERIMETER of parallelogram we will find the length of sides. ANSWER:- ⬤ Length of 1st side = 11 cm ⬤ Length of 2nd side = 33 cm ⬤ So, option C is correct. GIVEN:- ⟼ 1st side = 1x ⟼ 2nd side = 3x TO FIND:- ⟿ Length of the sides = ? FORMULA:- ➜ Perimeter = 2(a + b) [For finding the length of sides] SOLVING BY APPLYING THE FORMULA:- ⟼ 1st side = 1x ⟼ 2nd side = 3x ➜ Perimeter = 2(a + b) Finding the side:- Perimeter is 88 cm. So, ➜ 88 cm = 2(1x + 3x) Adding the terms:- 1x + 3x = 4x So, ➜ 88 cm = 2 × 4x Multiplying the terms:- 2 × 4x = 8x So, ➜ 88 cm = 8x Taking 8 to L.H.S:- 88 / 8 cm So, ➜ 88 / 8 cm = x Dividing the terms:- 11 / 1 So, ➜ 11/ 1 = x Final Answer:- 11 So, ➜ 11 = x Sides:- ➜ 1st side = 1x ⠀⠀⠀⠀⠀1x = 1 × 11 ⠀⠀⠀⠀⠀⠀⠀= 11 1st side is 11 cm. ➜ 2nd side = 3x ⠀⠀⠀⠀⠀⠀3x = 3 × 11 ⠀⠀⠀⠀⠀⠀ ⠀= 33 2nd side is 33 cm.

Adjacent sides of a parallelogram are in the ratio 1:3 and their perimeter is 88 cm then find the length of those sides. 1️⃣ 22,662️⃣ 20,60r3️⃣ 11,334️⃣ 10,30

Answer»

Solution:-

━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}$

$\implies$ Here it is given in the QUESTION that adjacent sides of a PARALLELOGRAM are in the ratio 1:3 and their perimetre is 88 cm. Now, the question has asked us to find out the length of those sides. So, to find the length of those sides, assume the adjacent sides as 1x and 3x. And after that by applying the formula of PERIMETER of parallelogram we will find the length of sides.

ANSWER:-

⬤ Length of 1st side = 11 cm

⬤ Length of 2nd side = 33 cm

⬤ So, option C is correct.

GIVEN:-

⟼ 1st side = 1x

⟼ 2nd side = 3x

TO FIND:-

⟿ Length of the sides = ?

FORMULA:-

➜ Perimeter = 2(a + b) [For finding the length of sides]

SOLVING BY APPLYING THE FORMULA:-

⟼ 1st side = 1x

⟼ 2nd side = 3x

➜ Perimeter = 2(a + b)

Finding the side:-

Perimeter is 88 cm.

So,

➜ 88 cm = 2(1x + 3x)

Adding the terms:- 1x + 3x = 4x

So,

➜ 88 cm = 2 × 4x

Multiplying the terms:- 2 × 4x = 8x

So,

➜ 88 cm = 8x

Taking 8 to L.H.S:- 88 / 8 cm

So,

➜ 88 / 8 cm = x

Dividing the terms:- 11 / 1

So,

➜ 11/ 1 = x

Final Answer:- 11

So,

➜ 11 = x

Sides:-

➜ 1st side = 1x

⠀⠀⠀⠀⠀1x = 1 × 11

⠀⠀⠀⠀⠀⠀⠀= 11

1st side is 11 cm.

➜ 2nd side = 3x

⠀⠀⠀⠀⠀⠀3x = 3 × 11

⠀⠀⠀⠀⠀⠀ ⠀= 33

2nd side is 33 cm.

VERIFICATION:-

➜ 2(11 cm + 33 cm)

➜ 2 × 44 cm

➜ 2 × 44 cm = 88 cm

➜ 88 cm

∴ L.H.S = R.H.S

Hence, verified.

Answer» ONG>Step-by-step EXPLANATION:

we KNOW that the SUM of adjacent angles of a parallelogram is equal to 180 degrees

so 3x+12 +2x-32=180

5x-20=180

5x=200

x=200/5

x=40

a=3x40+12

120+12

132

b=2x40-32

80-32

48

c=a=132

d=b=48

Answer»

ong>Answer:

142.5 ટાઇલ્સ

Step-by-step EXPLANATION:

લંબાઈ L = 3.8 m પહોળાઈ b = 6 m

લંબચોરસ ખંડનો વિસ્તાર = l × b = 3.8 × 6 = 22.8 m²

1 ટાઇલ્સની લંબાઈ l₀ = 25 સેમી = 0.4 m

1 ટાઇલનો વિસ્તાર = (l₀)² = (0.4)² = 0.16 m²

કુલ ટાઇલ્સ = ખંડનો વિસ્તાર / 1 ટાઇલનો વિસ્તાર = $\frac{22.8}{0.16}$ = 142.5 ટાઇલ્સ
