<h2>
The required "option A) 20" is correct.</h2>
Step-by-step explanation:
Let x be the smaller than 4 ×
.
To find, the number of times smaller is 2 × 
than 4 × = ?
∴ x = 
= 2 × × 
Using the identity,
= 2 × 
Using the identity,
= 2 × 
= 2 × 10
= 20
Thus, the required "option A) 20" is correct.

Step-by-step explanation:
Not completely sure. :<
H (4.84) will be the correct answer
We have that
<span>[6x+5]=1+2*(3x+2)
[6x+5]=1+2*3x+2 --------> is not correct ------->1+ 2*(3x+2)=1+2*3x+2*2
then
</span>[6x+5]=1+6x+4---------------> [6x+5]=[6x+5]
<span>this equation is an identity, all real numbers are solutions.</span>
