Let A be the set of all lines in the plane. Define a relation R on A as follows. For every l1 and l2 in A, l1 R l2 ⇔ l1 is paral
Lyrx [107]

Answer:

Hence, the relation R is a reflexive, symmetric and transitive relation.

Given :

A be the set of all lines in the plane and R is a relation on set A.

R=\{l_1,l_2\in A|l_1 \;\text{is parallel to}\; l_2\}

To find :

Which type of relation R on set A.

Explanation :

A relation R on a set A is called reflexive relation if every a\in A then (a,a)\in R.

So, the relation R is a reflexive relation because a line always parallels to itself.

A relation R on a set A is called Symmetric relation if (a,b)\in R then (b,a)\in R for all a,b\in A.

So, the relation R is a symmetric relation because if a line l_1 is parallel to the line l_2 the always the line l_2 is parallel to the line l_1.

A relation R on a set A is called transitive relation if (a,b)\in R and (b,c)\in R then (a,c)\in R for all a,b,c\in A.

So, the relation R is a transitive relation because if a line l_1 s parallel to the line l_2 and the line l_2 is parallel to the line l_3 then the always line l_1 is parallel to the line l_3.

Therefore the relation R is a reflexive, symmetric and transitive relation.

The length of a rectangle is 5 cm longer than its width.
blondinia [14]

Equation To write :2 {x+ ( x+5) }=30

Let's solve your equation step-by-step.

2(x+x+5)=30

Step 1: Simplify both sides of the equation.

2(x+x+5)=30

(2)(x)+(2)(x)+(2)(5)=30(Distribute)

2x+2x+10=30

(2x+2x)+(10)=30(Combine Like Terms)

4x+10=30

4x+10=30

Step 2: Subtract 10 from both sides.

4x+10−10=30−10

4x=20

Step 3: Divide both sides by 4.

4x

4

=

20

4

x=5

So... x+5=10.

Area =5x10=50 cm squared.
