Question

find x if 4,6,8,x are in proportion​

Answer 1

Step-by-step explanation:

ANSWER

Given the relation the relation R be defined on A as follows R={(a,a),(b,c),(a,b)}.

Now, to make this relation R to be reflexive we are to add the elements like (x,x) for all x∈A.

The the relation will be R={(a,a),(b,b),(c,c),(b,c),(a,b)}.

Now this relation is reflexive but not transitive as (a,b)∈A,(b,c)∈A⇒(a,c)



∈A.

Now to make this relation to be transitive we are to add (a,c).

Then the relation will be R={(a,a),(b,b),(c,c),(b,c),(a,b),(a,c)}

Answer 2

Answer:

Here is the answer:

Step-by-step explanation:

If 4,6,8,x are in proportion then x-8=8-6=6-4

So from here the common difference is 2

And x-8=2

x=8+2

x=10.

So the value of x is 10 and it is in proportion too.
