Factorise the following1) x^2 + 7x + 102) x^2 – 16x + 393) x^2 – 9x – 364) x^2 + 2x – 48​

Answer»

Answer:

\huge\underline\bold {Answer:}

1) x^2 + 7X + 10

=  {x}^{2}  + 5x + 2x + 10 \\  = x(x + 5) + 2(x + 5) \\  = (x + 5)(x + 2)

2) x^2 – 16X + 39

{x}^{2}  - 16x + 39 \\  =  {x}^{2}  - 13x - 3x + 39 \\  =x(x - 13) - 3(x - 13) \\  = (x - 3)(x - 13)

3) x^2 – 9x – 36

{x}^{2}  - 12x + 3x - 36 \\  = x(x - 12) + 3(x - 13) \\  = (x - 12)( x - 3)

4) x^2 + 2x – 48

=  {x}^{2}  + 8x - 6x - 48 \\  = x(x + 8) - 6(x + 8)  \\  = (x - 6)(x + 8)

Answer»

Answer:

let's x be there TOTAL no. of pens and y be the total no. of PENCILS

7x + 3y = 564.............eq 1

x + y = 108..................eq 2

solving eq 1 and eq 2 we get

7x + 3y = 564.............eq1 x 1

7x + 7Y = 756.................eq2 x 7

_____________

-4Y = - 192

y = 48

from equation 2 we get

x + 48= 108

x = 108 - 48

x = 60

therefore the person both 60 pens and 48 pencils

Answer:

the VALUE of b will be GIVEN in your question replace it with the LAST PART of the explanation, you will get the answer of the perimeter of the rectangle.

Step-by-step explanation:

LET the length be l.

let the breadth be b.

perimeter of a rectangle, P = 2(l+b)

therefore, P = 2(3b+b)

therefore, P = 2(4b)

therefore, P = 8b

Answer»

ANSWER:

The number is 35.

Step-by-step explanation:

Here is the CALCULATION for it:

Let the number be X

20% of x = 0.2 x

x+ 0.2x = 42

1.2 x =42

x = 42/1.2 =35

Hence, the number is 35.

That variesemesand00436. A part of monthly expenditure of a family is constant and the remainingvaries with the price of wheat. When the price of wheat is 800 perquintal, the total monthly expenditures is 5400 and when it is ? 1000per quintal, the total monthly expenditure ? 6000. Find the total monthlyexpenditure of the family when the cost of wheat is 950 per quintal​

Answer»

Answer:

The total monthly expenditure of the family when the cost of wheat is 950 per quintal is Rs. 5850

Step-by-step explanation:

Let the constant monthly expenditure be Rs.'x' and the amount of wheat they buy be 'y' Quintal

We KNOW that,

Monthly expense (constant) + (Rate × amount of wheat) = Total monthly expenditure

Now, According to the Question,

Case 1

x + 800y = 5400 ----- 1

Case 2

x + 1000y = 6000 ------ 2

Let's Subtract eq.1 from eq.2, we get,

x + 1000y = 6000

– x + 800y = 5400

————————————

0 + 200y = 600

————————————

y = 600/200 = 3

Putting y = 3 in eq.2 we get,

x + 1000(3) = 6000

x = 6000 - 3000 = 3000

Thus, the family has a monthly expense of

Rs.3000 and then buy's additional 3 Quintals of wheat

Now, If the rate of wheat COMES to Rs.950 per Quintal

then the family's total monthly expenditure = 3000 + 950(3) = 3000 + 2850 = Rs. 5850

Thus, the total monthly expenditure of the family when the cost of wheat is 950 per quintal is Rs. 5850

Hope it HELPED and you understood it........All the best

Two pole of heights 15m and 24m stand on a plane ground if the distance between their feet is 12 m find the distance between their tops15m25m14m36mI will give five star rating​

Answer»

ANSWER:

Hey there !!

→ Let the two poles AB and CD are STAND upright on the ground of 15M and 10m respectively.

→ AB is the distance between the tops of two poles is of 13m.

→ And, DB is the distance between their feet.

▶Now,

=> AE = AB - BE

=> AE = 15 - 10 . [ BE = CD ]

=> AE = 5m.

In ∆AEC,

➡ By Pythagoras theorem,

=> ( AC )² = ( AE )² + ( CE )².

=> (13)² = (5)² + (CE)².

=> 169 = 25 + (CE)².

=> (CE)² = 169 - 25.

=> CE = √144.

=> CE = 12m.

And, CE = BD.

So, BD = 12m. ( Distance between their feet ).

✔✔Hence, it is solved ✅✅.
