Given x = 3+2√2
x +1/x
= 3+2√2 + 1 / 3+2√2
= 3+2√2 + 3-2√2 / 3+2√2(3-2√2)
= 3+2√2 + 3-2√2 / 3² - (2√2)²
= 3+2√2 + 3-2√2/9-8
= 3+2√2 + 3-2√2
= 6 Which can be written in p/q forrm. (6/1)
Therefore it's a rational number!.

Y2-6y+9
= Y2-3y - 3y + 9
= y ( y - 3) - 3 ( y - 3)
= (y - 3) (y -3)

2x - 3y = 60 ------(1)
x + y = 180 ( Linear pair)
=> 3x + 3y = 540 ------(2)
On adding equation 1 and 2, we get
5x = 600
=> x = 120°
y = 180 - x
y = 180 - 120
y = 60°

Let radius=r cm
Height=h=25cm
Circumference of the cylinder=132cm
2*pi*r=132
r=(132*7)/(2*22)
r=21cm
Capacity of the vessel=volume of the vessel
=pi*r^2*h
=22/7*21*21*25
=34650cm^3
=34650*1/1000 li
[since 1cm^3= 1/1000 li]
=34.65li

The equations of two lines passing through (2, 14) can be taken as
x + y= 16
and 7x – y = 0.
There are infinitely many such lines because through a point an infinite number of lines can be drawn.

We know that Two angles are complementary if the sum of their degree measures equals 90 degrees.
x + y = 90 ----- (1).
Given that Difference of two complementary angles is 40.
x + y + x - y = 90 + 40
2x = 130
x = 65.
Substitute x = 65 in (1), we get
x + y = 90
65 + y = 90
y = 25.
The angles are 65 and 25.

To draw square root of 5 on a number line, following steps are to be followed.
Step 1: Draw a number line. Mark O as the zero on the number line.
Step 2: Mark a point A as -5 on the number line.
Step 3: Mark a point C as 1 on the number line.
Step 4: Mark a point B as the mid-point of AC.
Step 5: With point B as the centre and radius as AB draw a semicircle.
Step 6: From O draw a perpendicular line to the number line that intersects the previous drawn semi-circle at D. Here OD = square root of 5.
Step 7: With O as centre and radius as OD, draw an arc that intersects the number line at point E. Here E is the point square root of 5 on the number line.

27-4/3
= (∛27)-4
= 3-4
To remove negative sign we write as :

(b2 – 4ac) is called the discriminant of the quadratic equation ax2 + bx + c = 0. Its value determines the nature of roots
It is called the Discriminant, because it can "discriminate" between the possible types of answer: when b2 − 4ac is positive, we get two Real solutions. when it is zero we get just ONE real solution (both answers are the same) when it is negative we get a pair of Complex solutions.
