Answer:
-5x + 0y = -11
The y terms are eliminated
Step-by-step explanation:
- 4x – 2y = -2
X - 2y = 9
We want to subtract the second equation from the first
Distribute a minus sign to all the terms in the second equation
- 4x – 2y = -2
X - 2y = 9
= (-5x + 0y = -11)
800.000+60.000+3.000+100+40+1
Length of side of playground is 19.798 meter
<h3><u>Solution:</u></h3>
Given that a walkway forms one diagonal of a square playground
The walkway is 28 m long
<em><u>To find: To find length of side of playground</u></em>
The diagram is attached below
Consider the figure PQRS is a sqaure
Let us assume the length of side of the square is "a"
PQ forms the diagonal which is 28 m long
PQR forms a right angled triangle with PR as hypotenuse
And PQ and RQ forms the other two legs of right angled triangle
By pythogoras theorem,
The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
By above definition we get,
Thus the length of side of playground is 19.798 meter
The constructors that have an empty parameter are known as non-parameterized constructors.
What is non-parameterized constructors?
Non-parameterized constructors are those that only have one parameter, which is empty. Depending on the user, they are used to set the object's initial values to either specific constants or default values.
What is a parameterized constructor?
When a constructor takes a certain quantity of parameters, it is referred to as a parameterized constructor. to initialize class data members with unique values.
What does it mean to be parameterized and not?
These methods have a list of parameters or arguments that are passed a value by the caller method.
Methods that are not parameterized: These methods have no parameter list. Without passing any values to the function, the programmer can just call it.
