<h2>
Answer:</h2>
The number is -2.
<h2>
Step-by-step explanation:</h2><h3>Written out, our equation looks like this:</h3><h3>(-5·x)+2=12</h3>
We'll start of by taking our final result of 12 and subtracting 2, as the beginning of the statement says "two more."
<h3>12 minus 2 gives us
10.</h3>
Now, since the statement says "the product of -5," we will take this 10 and divide by -5.
<h3>10 divided by -5 gives us -2.</h3>
This means that our number, x equals -2. Of course, we must input this solution to double check our work.
<h3>(-5·<u>
-2</u>)+2=12</h3><h3>10+2=12</h3><h3>12=12</h3>
<h2>Our final answer is x=-2!</h2>

<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.
