4x^2-92x=9x^2 +126x;
5x^2+218x=0;
x(5x+218)=0;
X=0,-43.6, my calculation might be wrong tho you can’t check on your own

Step-by-step explanation:
A={1,2,3,4,5,6}
R={(x,y):y is divisible by x}
We know that any number (x) is divisible by itself.
(x,x)∈R
∴R is reflexive.
Now,(2,4)∈R [as 4 is divisible by 2]
But,(4,2)∈
/
R. [as 2 is not divisible by 4]
∴R is not symmetric.
Let (x,y),(y,z)∈R. Then, y is divisible by x and z is divisible by y.
∴z is divisible by x.
⇒(x,z)∈R
∴R is transitive.
Hence, R is reflexive and transitive but not symmetric.
Answer:
thirteen hundredths=13/100
one hundred thirty thousandths=130/1000
cancelling by 10 this is =13/100
hence the question

Step-by-step explanation:
9/b=21/14
9/b=3/2
9=3/2b
9=3b/2
9×2=3b
18=3b
18/3=b
6=b
b=6
