Answer» QUESTION : Find the VALUE (s) of m , when √m + 259 /√m = 44 Answer : ⇒ √m + 269 / √m = 44 Substituting √m = X in the above equation ⇒ x + 259 / x = 44 Multiplying every term by x ⇒ x( x ) + ( 259 / x )( x ) = 44x ⇒ x² + 259 = 44x ⇒ x² - 44x + 259 = 0 Splitting the MIDDLE term ⇒ x² - 37x - 7x + 259 = 0 ⇒ x( x - 37 ) - 7( x - 37 ) = 0 ⇒ ( x - 37 )( x - 7 ) = 0 ⇒ x - 37 = 0 or x - 7 = 0 ⇒ x = 37 or x = 7 When x = 37 ⇒ √m = 37 Squaring on both sides ⇒ ( √m )² = 37² ⇒ m = 1369 When x = 7 ⇒ √m = 7 Squaring on both sides ⇒ ( √m )² = 7² ⇒ m = 49 Therefore the value of m is either 1369 or 49.

☑ no spam ♨ ONLY ANSWER

Answer»

QUESTION :

Find the VALUE (s) of m , when √m + 259 /√m = 44

Answer :

⇒ √m + 269 / √m = 44

Substituting √m = X in the above equation

⇒ x + 259 / x = 44

Multiplying every term by x

⇒ x( x ) + ( 259 / x )( x ) = 44x

⇒ x² + 259 = 44x

⇒ x² - 44x + 259 = 0

Splitting the MIDDLE term

⇒ x² - 37x - 7x + 259 = 0

⇒ x( x - 37 ) - 7( x - 37 ) = 0

⇒ ( x - 37 )( x - 7 ) = 0

⇒ x - 37 = 0 or x - 7 = 0

⇒ x = 37 or x = 7

When x = 37

⇒ √m = 37

Squaring on both sides

⇒ ( √m )² = 37²

⇒ m = 1369

When x = 7

⇒ √m = 7

Squaring on both sides

⇒ ( √m )² = 7²

⇒ m = 49

Therefore the value of m is either 1369 or 49.

11.	A+b=10 and ab=4 find a2+b2
Answer» GIVEN: The value of a + b = 10 The value of ab = 4 TO FIND: The value of a² + b² SOLUTION: Squaring on both sides => (a + b)² = (10)² We know that, (a + b)² = a² + b² + 2ab (10)² = a² + b² + 2(ab) Substitute the value of ab 100 = a² + b² + 2(4) 100 = a² + b² + 8 => a² + b² = 100 - 8 => a² + b² = 92 Therefore, the value of a² + b² is 92.

11.

A+b=10 and ab=4 find a2+b2

Answer»

GIVEN:

The value of a + b = 10

The value of ab = 4

TO FIND:

The value of a² + b²

SOLUTION:

Squaring on both sides

=> (a + b)² = (10)²

We know that,

(a + b)² = a² + b² + 2ab

(10)² = a² + b² + 2(ab)

Substitute the value of ab

100 = a² + b² + 2(4)

100 = a² + b² + 8

=> a² + b² = 100 - 8

=> a² + b² = 92

Therefore, the value of a² + b² is 92.

Answer»

$\huge\underline{ \underline{ \bf{ \blue{ \: solution \: : = }}}}$

by USING QUADRATIC formula,

$\bf {\boxed{\frac{ -b + - \sqrt{ {b }^{2} - 4ac} }{2a}}}$

⠀⠀⠀⟹⠀ $x = \frac{ - ( - 4) + - \sqrt{ - 4 {}^{2} - 4 \times 5 \times ( - 7)} }{2 \times 5}$

⠀⠀⟹⠀⠀ $x = \frac{ - 4 + - \sqrt{16 - 4 \times 5( - 7)} }{10}$

⠀⠀⠀⠀⟹⠀⠀ $x = \frac{4 + - \sqrt{16 - 140} }{10}$

⠀⠀⠀⟹⠀⠀ $x = \frac{4 + - \sqrt{156} }{10}$

⠀⠀⠀⠀⟹⠀⠀ $x = \frac{4 + \times 2 \sqrt{39} }{10}$

⠀⠀⠀⠀⟹⠀⠀ $x = \frac{2 \sqrt{39} + 4 }{10}$

⠀⠀⠀⟹⠀⠀ ${\bf{\boxed{\pink{x = \frac{ \sqrt{39} + 2}{ 5}}}}}$

⠀⠀⠀⠀⟹⠀ $x = \frac{ - 4 - 2 \sqrt{39} }{10}$

Answer» Answer: your answer is here Step-by-step explanation: Let the ones digit be x and the TENS digit be y. Then, Number= (10y + x) A/q x + y = 9................(i) And, 10y + x - 27 = 10X + y => 10y - y + x - 10x = 27 => 9y - 9x = 27 => 9 ( y - x ) = 27 => y - x = 3...............(ii) Now, By adding eq. (i) and (ii), we get x + y = 9 - x + y = 3 ---------------- 2y = 12 ( y = 6 ) Now, put the value of y = 6 in eq. (i) x + y = 9 x + 6 = 9 x = 9 - 6 ( x = 3 ) Then, Number = 10y + x = 10 ( 6 ) + 3 = 60 + 3 = 63.............Answer. Hence, The required number is 63. please mark me BRAINLIEST

Answer:

your answer is here

Step-by-step explanation:

Let the ones digit be x and the TENS digit be y.

Then, Number= (10y + x)

A/q

x + y = 9................(i)

And, 10y + x - 27 = 10X + y

=> 10y - y + x - 10x = 27

=> 9y - 9x = 27

=> 9 ( y - x ) = 27

=> y - x = 3...............(ii)

Now, By adding eq. (i) and (ii), we get

x + y = 9

- x + y = 3

----------------

2y = 12

( y = 6 )

Now, put the value of y = 6 in eq. (i)

x + y = 9

x + 6 = 9

x = 9 - 6

( x = 3 )

Then, Number = 10y + x

= 10 ( 6 ) + 3

= 60 + 3

= 63.............Answer.

Hence, The required number is 63.
