Solve for X and y 139x+56y=641 ,56x+139y=724​

Answer»

Step-by-step explanation:

Let the given equations be ;

139x + 56y = 641 -------- (1)

56x + 139y = 724 --------- (2)

On adding EQ. 1) & 2) we get ;

195x + 195y = 1365

195(X + y) = 1365 [ on taking 195 as common ]

x + y = 1365/195

x + y = 7 ------- (3)

Now, SUBTRACTING eq.2) from 1) we get,

83x - 83y = -83

83 (x - y ) = -83

x - y = -83/83

x - y = -1 ------- (4)

Adding eq.3) and 4) we get ;

2x = 6

x =3

On putting value of "x" in eq.4) we get ;

3-y = -1

y = 4

Find the sum of arithmetic sequence which contains 25 terms and whose middle term is 20​

Answer»

SOLUTION ☺️

25 terms which is odd terms

so, the middle term = (n+1)/2th term

=) 25+1/2

=) 26/2

=) 13th term

A/q

=) 13th term= 20term

=) a+12d= 20..........(1)

Sum of the series= n/2[2a+(n-1)d]

=) 25/2[2a+(25-1)d]

=) 25/2×2[a+12d]

=) 25[a+12d]

=) 25(20)......(using EQUATION 1)

=) 25×20

=) 500

the length of rectangle is three times its breath.if the perimeter of the rectangle is 40cm,find the length and breadth of the rectangle​

Answer»

Answer:

\large{\underline{\boxed{\sf <klux>LENGTH</klux> = 15 \: cm}}}

\large{\underline{\boxed{\sf Breadth = 5 \: cm}}}

Step-by-step explanation:

Let the breadth of rectangle be x and the length be 3X.

Given that ;

Perimeter of rectangle = 40 cm

⇒ 2(l + B) = 40

⇒ l + b = 40/2

⇒ 3x + x = 20

4X = 20

⇒ x = \sf \dfrac{20}{4}

⇒ x = 5

Therefore, the dimensions of rectangle are;

  • Length = 3x = 3 * 5 = 15 cm
  • Breadth = x = 5 cm.

Hence, the length of the rectangle is 15 cm and breadth is 5 cm.

If the pair of linear equations in two variables 2x+3y=4, 2ax+(a+b)y=28 are consistent and dependent then prove that b=2a

Answer»

Step-by-step EXPLANATION:

HEY there!!!!!

if the PAIR is consiaitent then,

in

2x+3y=4,2ax+(a+b)y=28

2/2a=4/28

2×28=4×2a

8a=56

a=7

now,

3/a+b=4/28

84=4(a+b)

a+b=21

7+b=21

b=14

if,

a=7 and b=2×7

then b=2a

Factorise x 4 +2x 3-13x 2-14x+24

Answer»

Answer:

(x-1) (x+2) (x-3) (x+4)

Step-by-step explanation:

Firstly, we will find the root of p(x) = x^4 + 2x³ - 13x² - 14x + 24

When x = 1

=> x^4 + 2x³ - 13x² - 14x + 24

=> (1)^4 + 2(1)³ - 13(1)² - 14(1) + 24

=> 1 + 2 - 13 - 14 + 24

=> 27 - 27

=> 0

So by factor theorem, (x - 1) is a factor

On dividing p(x) by (x - 1), we get + 3x² - 10x -24

Refer to the attachment 1

Now find the root of p(x) = x³ + 3x² - 10x -24

When x = -2

=> x³ + 3x² - 10x -24

=> (-2)³ + 3(-2)²- 10(-2) -24

=> -8 + 12 + 20 - 24

=> -32 + 32

=> 0

So by factor theorem, (x + 2) is a factor

On dividing p(x) by (x + 2), we get x² + x - 12

☆ Refer to the attachment 2

Now, USING middle term splitting :

=> x² + x - 12

=> x² + 4x - 3x - 12

=> x(x+4) - 3(x+4)

=> (x-3) (x+4)

∴ x^4 + 2x³ - 13x² - 14x + 24 = (x-1) (x+2) (x-3) (x+4)

Area of a rectangular field whose length is twice its breadth is 2450m Find the area ofsquare field whose perimeter is equal to the perimeter of the rectangular field.​

Answer»

let the length and BREADTH of rectangle be 2x and X, respectively

A. T. Q.

2x*x=2450

2(x)^{2}  = 2450

{x}^{2}  = 1225

x=35

the length=70 and breadth =35

Now,

perimeter of rectangle=2(l+b)

=2(35+ 70)

= 2*105

=210

Again,

perimeter of square=210

side*4=210

side. =52.5

now again,

area  of square  \:  {side}^{2}

{52.5}^{2}

2756.25.
