a2 - b2 = (a-b)(a +b)
75x²-27
= 3(25x2 - 9)
= 3[(5x)2 - (3)2]
= 3 (5x - 3) (5x + 3)

a2 - b2 = (a-b)(a +b)
24a²-54b²
= 6 [4a²-9b²]
= 6[(2a)2 - (3b)2]
= 6 (2a - 3b) (2a+3b)

a2 - b2 = (a-b)(a +b)
36(a+b)²-49(a-b)²
= [6(a+b)]²-[7(a-b)]²
= [ 6(a + b) - 7(a-b) ] [ 6(a + b)+ 7(a-b) ]

Let the two numbers be x and y such that x>y..
Now according to the question-
Condition I:-
x+y=80.....(1)
Condition II:-
x=2y+11.....(2)
Substituting the value of x in eqn(1) we have
(2y+11)+y=80
3y+11=80
3y=80−11
y=69/3 =23
Substituting the value of y in eqn(2), we have
x=2×23+11
⇒x=46+11=57
Hence the required numbers are 57 and 23.

Let the first multiple of 8 be 8x.
Therefore the second consecutive multiple of 8 will be 8(x+1)
Also the third consecutive multiple of 8 will be 8(x+2).
It is given that the sum of these three consecutive multiples of 8 is 888
=> 8x + 8(x+1) + 8(x+2) = 888
=> 8x + 8x + 8 + 8x + 16 = 888
=> 24x + 24 = 888
Take 24 on the RHS
=> 24x = 888 - 24
=> x = 864/24
=> x = 36.
Therefore First multiple of 8 be 8x = 8 x 36 = 288
Second Multiple of 8 be 8(x + 1) = 8(36 + 1) = 8 x 37 = 296
Third Multiple of 8 be 8(x + 2) = 8(36 + 2) = 8 x 38 = 304
If we sum up these three multiples i.e (288 + 296 + 304) we get 888.

A polygon is a simple closed curve made up entirely of line segments.
A polygon has at least 3 sides.
The line segments forming a polygon are called its sides and the points at which the sides meet are called vertices.

Any number that can be written as a fraction with integers is called a rational number . For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.
Types of Rational Numbers
- Real numbers (R) include all the rational numbers (Q).
- Real numbers include the integers (Z).
- Integers involve natural numbers(N).
- Every whole number is a rational number because every whole number can be expressed as a fraction.

let the original edge be x
volume = x³
if the edge is doubled,
then edge is 2x
volume = (2x)³ = 8x³
therefore,
= 8
the volume will increase 8 times.
