The factors of a^2-b^2-4c^2+4d^2-4(ad-bc) are

Answer»

Given \:a^{2} - b^{2}-4c^{2} + 4d^{2} - 4(ad-bc)

= \:a^{2} - b^{2}-4c^{2} + 4d^{2} - 4ad+ 4bc

/* REARRANGING the TERMS, we GET */

= a^{2} + 4d^{2} - 4ad - b^{2} - 4c^{2} + 4bc

= (a^{2} + 4d^{2} - 4ad) - (b^{2} +4c^{2} -4bc )

= [a^{2} + (2d)^{2} - 2\times a \times (2d)] - [b^{2} +(2c)^{2} - 2\times b \times (2c )]

= ( a - 2d )^{2} - ( b - 2c)^{2}

= [ (a-2d) + ( b - 2c ) ] [ (a-2d) - ( b - 2c ) ] \\= (a-2d+b-2c)(a-2d-b+2c) \\= ( a+b-2c-2d)(a-b+2c-2d)

THEREFORE.,

3x-y=6and2x-y=-1solve by substitution metheod​

Answer»

GIVEN equations

3x-y=6\\\implies -y=6-3x\\\implies y = 3x-6

2x-y=-1

SUBSTITUTING the VALUE of y, we GET,

\implies 2x-(3x-6)=-1\\\implies 2x-3x+6=0\\\implies -<klux>X</klux>+6=0\\\implies -x=-6\\\implies x= 6

Substituting the value of x, we get,

y = 3(6)-6\\\implies y = 18-6\\\implies y = 12

\boxed{\boxed{\bold{Therefore, \ the \ values \ of \ x \ and \ y \ are \ 6 \ and \ 12 \ respectively}}}}}}}}}}

Answer»

Answer:

56

1) Let the number of BOYS be 7x and girls be 5x.

2) Therefore 7x = 5x + 8, 2x = 8, X = 4.

3) No. of boys = 7x + 8 = 7 × 4 + 8 = 36.

4) No. of girls = 5x = 5 × 4 = 20.

38.

Plz help me in this numerical ​

Answer»

Step-by-step explanation:

Given :-

a)2x + y = 7......(1)

On putting X=0 in equation 1

2x+y=7

2×0+y=7

0+y=7

Y=7

So( 0, 7) is a solution of given equation.

let y=0

2x+y=7

2x+0=7

2x=7

X= 7/2

So(7/2,0) is a solution of given equation.

 

let x = 1

 

2x+y=7

2×1+y=7

2+y=7

Y= 7-2

Y=5

(1,5) is the solution.

 

let x = 2

2x+y=7

2×2+y=7

4+y=7

Y= 7-4

Y= 3

The solution is (2,3)

HENCE, 4 out of the infinitely many solutions of the given equation are(0,7), (7/2,0),(1,5),(2,3)

A can do a peice of work in 15 days and B in 20 days .If they together work on it for 4 days .then the fractions of work is left​

Answer»

ANSWER:

A can do a work in 15 days and B in 20 days

A can do the work in 15 days.

Thus A finishes in ONE DAY = 1/15 work.

B finishes in one day = 1/20 work

Together, they finishes in one day

1/15 + 1/20 =7/60 work

If they work together for 4 days then what is the fraction of work that is left?

In 4 days they will finish work = 4 × 7/60 = 7/15 work

Remaining work left = 1 - 7/15

= (15 - 7)/15

= 8/15

The fraction of work left is 8/15

Answer : The fraction of work left is 8/15

The formula for finding the SUM of CUBES of 'n' numbers is

(\frac{n(n +1)}{2} )^{2}

Here n = 10.

Therefore, the sum is

(\frac{10(10 + 1)}{2}) ^{2} =(\frac{10*11}{2}) ^{2} = (5*11)^{2} =55^{2}
