Answer:

Step-by-step explanation:

2x²+5√3 x+6 = 0

Comparing this with quadratic equation ax^2+bx+c=0

So a=2,b=5√3,c=6

Discriminant D=b^2-4ac

D=(5√3)^2-4.2.6

= 75-48

=27.

27 >0

Hence the roots are real roots

X=(-b+√D)/2a, Y=(-b-√D)/2a

X=(-5√3+√27)/2×2, Y=(-5√3-√27)/2×2

X=(-5√3+3√3)/4,. Y=(-5√3-3√3) /4

X=-2√3/4,. Y=-8√3/4

X=-√3/2, Y =-2√3

So roots are X=-√3/2,Y=-2√3

Answer:

x = 6

Step-by-step explanation:

When 2 chords of a circle intersect then the product of the parts of one is equal to the product of the parts of the other, that is

2x = 3 × 4, that is

2x = 12 ( divide both sides by 2 )

x = 6

In the figure below, AMNO

NeX [460]

Given:

$\Delta MNO\cong \Delta PQR$

To find:

The length of QR.

Solution:

We have,

$\Delta MNO\cong \Delta PQR$

Then, $MN=PQ$ (CPCTC)

$10=4x-2$

$10+2=4x$

$12=4x$

Divide both sides by 4.

$\dfrac{12}{4}=x$

$3=x$

Similarity,

$MO=PR$ (CPCTC)

$2y+3=21$

$2y=21-3$

$2y=18$

Divide both sides by 2.

$y=9$

Now,

$x+y=3+9$

$x+y=12$

Therefore, the correct option is d.
