Verify : x³ + y³ = (x + y)(x² - xy + y²)And on this basis simplify :27y³ + 125z³

Answer»

>Solution :

$\:$

Verify : x³ + y³ = (x + y)(x² - xy + y²)

$\:$

☞︎︎︎ x³ + y³ = x(x² - xy + y²) + y(x² - xy + y²)

$\:$

Distributive Property

$\:$

⟹ x³ + y³ = ( x³ - x²y + xy²) + (yx² - xy² + y³)

$\:$

Cancel the like terms with opposite sign..

$\:$

$\rm = ( x³ \cancel{ - x²y} + xy²) + ( \cancel{x²y} - xy² + y³)$

$\:$

$\rm = ( x³ { } + \cancel{ xy²}) + ( {} \cancel{ - xy²} + y³)$

$\:$

☞︎︎︎ x³ + y³ = x³ + y³

$\:$

☆ Now :

$\:$

i) 27y³ + 125z³

< Simplify = Factorise >

$\:$

☞︎︎︎ Using IDENTITY-

x³ + y³ = ( x³ - x²y + xy²) + (yx² - xy² + y³)

$\:$

⟹ 27y³ + 125z³ = (3y)³ + (5Z)³

$\:$

a = 3y

b = 5z

$\:$

⟹ (3y)³ + (5z)³ = (3y + 5z) [(3y)² - (3y)(5z) + (5z)²]

$\:$

= (3y + 5z)(9y² - 15YZ + 25z²)

20.	adjacent sides of a parallelogram are in the ratio 1 ratio 3 and their perimeter is 88 CM then find the length of the side
Answer» Answer:- One SIDE = 11 cm. ANOTHER adjacent side = 33 cm. Given:- RATIO of the adjacent sides of parallelogram are 1 : 3. Perimeter of parallelogram is 88 cm. To Find:- The length of sides. Solution:- Here, Let the ratio constant be $x$ . Then, One side = $x$ cm and, Another adjacent side = $3x$ cm. Since, We know that opposite sides of parallelogram are equal. Now, $x + x + 3x + 3x = 88 \ cm$ ⇒ $8x = 88 \cm$ ⇒ $x = \dfrac{88}{8}$ ⇒ $x = 11$ So, One side = 11 cm and, Another adjacent side = 3 × 11 = 33 cm Some IMPORTANT Terms:- Area of Parallelogram = Base × Height Area of Rectangle = Length × Breadth Perimeter of Rectangle = 2( L + B )

20.

adjacent sides of a parallelogram are in the ratio 1 ratio 3 and their perimeter is 88 CM then find the length of the side

Answer»

Answer:-

One SIDE = 11 cm.

ANOTHER adjacent side = 33 cm.

Given:-

RATIO of the adjacent sides of parallelogram are 1 : 3.

Perimeter of parallelogram is 88 cm.

To Find:-

The length of sides.

Solution:-

Here, Let the ratio constant be $x$ .

Then, One side = $x$ cm

and, Another adjacent side = $3x$ cm.

Since, We know that opposite sides of parallelogram are equal.

Now, $x + x + 3x + 3x = 88 \ cm$

⇒ $8x = 88 \cm$

⇒ $x = \dfrac{88}{8}$

⇒ $x = 11$

So, One side = 11 cm

and, Another adjacent side = 3 × 11

= 33 cm

Some IMPORTANT Terms:-

Area of Parallelogram = Base × Height

Area of Rectangle = Length × Breadth

Perimeter of Rectangle = 2( L + B )
