Answer:
The surface area increased by 125%.
Step-by-step explanation:
Let the initial side length be x. Then the surface area of cube is
If each side of a cube is increased by 50%, then the new side length is
The surface area of new cube is
The percentage increase in its surface area is
Therefore the surface area increased by 125%.

Let us consider that 2 distinct circles intersect at more than 2 points.
∴These points are non-collinear points.
As 3 non-collinear points determine one and only one circle
∴There should be only one circle.
(i.e. those circles are supposed to superimpose each other)
But, the superimposition of 2 circles of different radii is impossible, i.e. concentric circles would be derived instead.
This contradicts our assumption. Therefore, our assumption is wrong.
Hence, 2 circles cannot intersect each other at more than 2 points.

Given that,
Two numbers, .
To find,
A rational number between .
Solution,
Numbers that can be expressed in the form of where p and q are integers and q is not equal to 0 are called rational numbers.
We know that, and
We need to find a rational number between it means that we need to find a number between 1.41 and 1.73.
So, it is very clear that a number between 1.41 and 1.73 is 1.5.
So, a rational number between is 1.5.

Let coefficient of ratios be X
a = 3x
b = 4x
c = 5x
Using Heron's Formula,
s = (3+4+5)x/2 = 12x/2 = 6x
Now,
a = 5*3 = 15 cm
b = 5*4 = 20 cm
c = 5*5 = 25 cm
Perimeter = 15+20+25 = 60 cm

Let the measure of the required angle be x°.
Then, the measure of its complement =(90−x)°.
And the measure of its supplement=(180−x)°.
Therefore,
7(90−x)=3(180−x)−10
⇒630−7x=540−3x−10
⇒4x=100
⇒x=25
Hence, the measure of the required angle is 25°.

The polynomial 0 has no terms at all, and is called a zero polynomial. Because the zero polynomial has no non-zero terms, the polynomial has no degree.

For an isosceles right angled triangle each having equal side 'a'
Using Pythagoras theorem,
AC2 = AB2 + BC2 where AB = BC = a
AC2 = a2 + a2
AC2 = 2a2
AC = √2a
Semi perimeter of a triangle ABC = (a + a + √2a)/2 = (√2+1)a/√2

a n s w e r
(a+b)^3 = a^3 + b^3 +3a b^2 + 3ba^2 as shown below:
(a+b)^3 = (a+b) (a+b)^2 = (a+b)(a^2 + 2ab + b^2)
=a^3 +2a^2 b + ab^2 + ba^2 +2ab^2 + b^3
= a^3 + 3a b^2 + 3 b a^2 + b^3 and I it is often written as
a^3 + 3ab(a+b) + b^3

Surface area of cube is given by the formula 6a²
So 6a² = 384
a² = 384/6 = 64
a = √64 = 8
The formula to find the volmue of cube is a³
So we know that a = 8
8³ = 512m³
The volume is 512m³

3x²+x-2
= 3x²+3x- 2x -2
= 3x(3 x + 2) - 2 ( x + 2)
= (3x - 2) ( x + 2)
