9.

Check whether 3 and -2 are the zeros of the polynomial p(x)=x2-×-6

Answer»

p(x) = x2 × (-6)

=> put 3 in place of x

3 = (3×2) × (-6)

3= 6× -6

3= - 36

= -36/3

= -12.

p(x) = x2 × (-6)

=> put -2 in place of x

-2= (-2 × 2) × (-6)

-2= -4 × -6

Answer» Step-by-step EXPLANATION: ANSWER Let the LENGTH and breadth of the rectangle be x and y units respectively. Then, Area =XY sq. units. If length is reduced by 5 units and the breadth is increases by 3 units, then area is reduced by 9 square units. ∴xy−9=(x−5)(y+3) ⇒xy−9=xy+3x−5y−15 ⇒3x−5y−6=0 ...(i) When length is increased by 3 units and breadth by 2 units, the area is increased by 67 sq. units. ∴xy+67=(x+3)(y+2) ⇒xy+67=xy+2x+3y+6 ⇒2x+3y−61=0 ...(ii) Thus, we GET the following system of LINEAR equations: 3x−5y−6=0 2x+3y−61=0 By using cross-multiplication, we have 305+18 x = −183+12 −y = 9+10 1 ⇒x= 19 323 =17 and y= 19 171 =19 Hence, the length and breadth of the rectangle are 17 units and 19 units respectively.

(v) The area of a rectangle gets reduced by 9 square units, if its length is reduced by5 units and breadth is increased by 3 units. If we increase the length by 3 units andthe breadth by 2 units, the area increases by 67 square units. Find the dimensionsof the rectangle.Plz answer, Dont spam!!

Answer»

Step-by-step EXPLANATION:

ANSWER

Let the LENGTH and breadth of the rectangle be x and y units respectively. Then,

Area =XY sq. units.

If length is reduced by 5 units and the breadth is increases by 3 units, then area is reduced by 9 square units.

∴xy−9=(x−5)(y+3)

⇒xy−9=xy+3x−5y−15

⇒3x−5y−6=0 ...(i)

When length is increased by 3 units and breadth by 2 units, the area is increased by 67 sq. units.

∴xy+67=(x+3)(y+2)

⇒xy+67=xy+2x+3y+6

⇒2x+3y−61=0 ...(ii)

Thus, we GET the following system of LINEAR equations:

3x−5y−6=0

2x+3y−61=0

By using cross-multiplication, we have

305+18

x

=

−183+12

−y

=

1

⇒x=

=17 and y=

=19

Hence, the length and breadth of the rectangle are 17 units and 19 units respectively.

Answer» X+4y =10 ........1 2x-2y =2.........2 form eq1 x= 10-4y 2x-2y =2 divide eq2 by 2 x-y = 1 ...........3 put x in eq3 10-4y -y = 1 -5y = 1-10 -5y = -9 y= 9/5 put y in x x= 10-4× 9/5 x= 10 - 36 /5 x= 50 -36 /5 x= 14 /5

37.

X+4y =10 and 2x-2y =2

Answer»

X+4y =10 ........1

2x-2y =2.........2

form eq1

x= 10-4y

2x-2y =2

divide eq2 by 2

x-y = 1 ...........3

put x in eq3

10-4y -y = 1

-5y = 1-10

-5y = -9

y= 9/5

put y in x

x= 10-4× 9/5

x= 10 - 36 /5

x= 50 -36 /5

x= 14 /5

Answer» Step-by-step EXPLANATION: Given:- $\sf(<klux>X</klux> - 2) : (x + 2) = (x + 3) : (x + 11)$ To Find:- The value of x Solution:- $\sf(x - 2) : (x + 2) = (x + 3) : (x + 11)$ $\sf \implies \dfrac{x - 2}{x + 2} = \dfrac{x + 3}{x + 11}$ By cross multiplication:- $\sf \implies (x - 2)(x + 11)= (x + 3)(x + 2)$ $\sf \implies x(x + 11) - 2(x + 11)= x(x + 2) + 3(x + 2)$ $\sf \implies {x}^{2} + 11x - 2x - 22= {x}^{2} + 2x+ 3x + 6$ $\sf \implies {x}^{2} + 9x - 22= {x}^{2} + 5x + 6$ $\sf \implies {x}^{2} - {x}^{2} + 9x - 5x - 22 - 6 = 0$ $\sf \implies 4x - 28 = 0$ $\sf \implies 4x = 28$ $\sf \implies x = \dfrac{28}{4}$ $\sf \implies x = 7$ $\longrightarrow \underline{\boxed{\rm \therefore \: The \: value \: of \: x = 7 }}$ LET'S Check:- Substitute x = 7 in $\sf (x - 2)(x + 11)= (x + 3)(x + 2)$ $\sf \implies (7 - 2)(7 + 11)= (7 + 3)(7 + 2)$ $\sf \implies 5 \times 18 = 10 \times 9$ $\sf \implies 90 = 90$ LHS = RHS Hence Verified

(x-2) : (x+ 2) = (x +3) : (x + 11) then find value x

Answer»

Step-by-step EXPLANATION:

Given:-

$\sf(<klux>X</klux> - 2) : (x + 2) = (x + 3) : (x + 11)$

To Find:-

The value of x

Solution:-

$\sf(x - 2) : (x + 2) = (x + 3) : (x + 11)$

$\sf \implies \dfrac{x - 2}{x + 2} = \dfrac{x + 3}{x + 11}$

By cross multiplication:-

$\sf \implies (x - 2)(x + 11)= (x + 3)(x + 2)$

$\sf \implies x(x + 11) - 2(x + 11)= x(x + 2) + 3(x + 2)$

$\sf \implies {x}^{2} + 11x - 2x - 22= {x}^{2} + 2x+ 3x + 6$

$\sf \implies {x}^{2} + 9x - 22= {x}^{2} + 5x + 6$

$\sf \implies {x}^{2} - {x}^{2} + 9x - 5x - 22 - 6 = 0$

$\sf \implies 4x - 28 = 0$

$\sf \implies 4x = 28$

$\sf \implies x = \dfrac{28}{4}$

$\sf \implies x = 7$

$\longrightarrow \underline{\boxed{\rm \therefore \: The \: value \: of \: x = 7 }}$

LET'S Check:-

Substitute x = 7 in $\sf (x - 2)(x + 11)= (x + 3)(x + 2)$

$\sf \implies (7 - 2)(7 + 11)= (7 + 3)(7 + 2)$

$\sf \implies 5 \times 18 = 10 \times 9$

$\sf \implies 90 = 90$

LHS = RHS

Hence Verified
