A shape that has all sides equal and all angles right angles is called a square.
In a square, all four sides are congruent (equal in length) and all four angles are right angles (90 degrees).
A square is also a special case of a rectangle, which is a four-sided polygon with opposite sides parallel and equal in length. In rectangle, all angles are right angles (90 degrees).
A square is also special case of a rhombus, which is a four-sided polygon with opposite sides parallel and equal in length, but all angles are not necessarily right angles.
A square is also special case of a parallelogram, which is a four-sided polygon with opposite sides parallel and equal in length, but all angles are not necessarily right angles.

What is the nature of the roots of the quadratic equation 5x² 4x 1?.
Since there are two complex conjugates as the roots of the quadratic equation 5x2 4x 3 0 there is no way to describe them in terms of real integers.
The roots can only be roughly calculated because they are irrational numbers.
Two complex conjugates, which are unable to be expressed in terms of real numbers, make up the roots of the quadratic equation 5x2 4x 3 0. Using the quadratic formula, the roots can be discovered. The coefficients of the equation are necessary for the formula, and in this example, they are a=5, b=4, and c=3. When the quadratic formula is used, two complex roots are produced, denoted by the expressions x1 = -1/5 + (16)/5i and x2 = -1/5 - (16)/5i. Since their roots are irrational integers, they can only be roughly calculated. When b2-4ac, the discriminant, is negative, complex roots are frequently discovered. The discriminant in this situation is -64, which is negative and shows that the equation has complex roots.
Inequality = b2-4ac = 42-4(5)(3) = -64.

How do you graph the absolute value of y absolute value X?.
The process to sketch the graph of y = absolute value x is explained below .
What is Absolute Value ?
The absolute value of a number is the distance of the number from origin of a number line. It is denoted as |a|, which defines the magnitude of any integer "a". Absolute Value is represented by two vertical lines "|a|" , which is called as modulus of a .
we have to sketch the graph of the absolute function given as ; y = |x| ;
put x = -2 , we get ⇒ y = 2 ;
put x = 2 , we get ⇒ y = 2 ;
we see that if we put any value of "x" , positive or negative , the result "y" will always be positive .

How much greater is the intensity of an earthquake that measures 3 on the Richter scale than and earthquake that measures 1?.
The intensity of an earthquake that measures 3 on the Richter scale than and earthquake that measures 1 is 31*2 times greater.
Every whole number measurement releases energy that is around 31 times more than the previous whole number measurement. A magnitude 2 earthquake is thus 31 times more violent than a magnitude 1 earthquake, for instance.
The Richter scale, also known as the Richter's magnitude scale, Richter's scale, and the Gutenberg-Richter scale, was created by Charles Francis Richter and first published in his seminal 1935 paper under the name "magnitude scale." Charles Richter created the base-10 logarithmic Richter scale in the 1930s.

Step-by-step explanation:
if x=3 and y=8, then the value of 5xy is
Answer:120
Step-by-step explanation:
given x= 3 and y= 8,
we have to find the value of 5xy
so let us put the values of x and y in the given expression i.e 5xy.2
= 5×3×8
= 120
Hence the value of 5 xy is 120.
Answer:
Step-by-step explanation:
If x = 3 and y = 8, then the value of 5xy is simply 5 times the product of x and y.
To find the product of x and y, we simply multiply x and y together:
xy = 3 * 8 = 24
To find the value of 5xy, we simply multiply 5 by the value of xy:
5xy = 5 * 24 = 120
So the value of 5xy when x = 3 and y = 8 is 120

As the die is fair the maximum number you can get on each die is 6 so even if we get both die's to roll on its maximum (6, 6) we still won't get a number above 12, so the probability of getting a number above 12 is impossible.
Find the inverse of the function.
f(x)=9x², x ≤ 0
The inverse of a function "swaps" the x and y values of the original function. To find the inverse of f(x) = 9x², we need to switch the x and y values and solve for x in terms of y:
y = 9x²
To find the inverse function we must isolate x.
x = √(y/9)
So the inverse of the function f(x) = 9x², x ≤ 0 is f^-1(x) = √(x/9), x ≤ 0.
Answer:
[tex]f^{-1}(x)=\dfrac{\sqrt{x}}{3}, \quad x \leq0[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=9x^2[/tex]
The domain of the given function is restricted: {x : x ≤ 0}
The range of the given function is restricted: {f(x) : f(x) ≤ 0}
To find the inverse of a function, swap x and y:
[tex]\implies x=9y^2[/tex]
Rearrange the equation to make y the subject:
[tex]\implies x=3^2y^2[/tex]
[tex]\implies x=(3y)^2[/tex]
[tex]\implies \pm\sqrt{x}=3y[/tex]
[tex]\implies y=\dfrac{\pm\sqrt{x}}{3}[/tex]
As x ≤ 0 then:
[tex]\implies y=\dfrac{\sqrt{x}}{3}[/tex]
Replace y with f⁻¹(x):
[tex]\implies f^{-1}(x)=\dfrac{\sqrt{x}}{3}[/tex]
The domain of the inverse of a function is the same as the range of the original function. Therefore, the domain of the inverse function is restricted to {x : x ≤ 0}.

the ages of two brothers are in the ratio 8:3 in 3 years time their ages will be in the ratio 9:4 find the differences between their ages in simultaneous equation
The differences between their ages is equal to 15 years.
How to determine the differences between their ages?Since the ages of two brothers are in the ratio 8:3, the age of the first (1st) brother would be represented by 8x while the age of second (2nd) brother would be represented by 3x.
Note: The variable x represents the age in years.
After 3 years, the age of the first (1st) brother would be represented by 8x + 3. Similarly, the age of second (2nd) brother would be represented by 3x + 3.
Translating the word problem into an algebraic equation by using ratios, we have the following:
(8x + 3)/(3x + 3) = 9/4
4(8x + 3) = 9(3x + 3)
32x + 12 = 27x + 27
32x - 27x = 27 - 12
5x = 15
x = 15/5
x = 3.
Now, we can determine the age of the brothers;
First brother's age = 8x = 8 × 3 = 24 years.
And, 2nd brother's age = 3x = 3 × 3 = 9 years.
For the difference, we have:
Difference = 24 - 9
Difference = 15 years.
