Answer:

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>given:</h3>
<h3>to find:</h3>
<h3>let's solve:</h3>

A-5B=2x+3-5(x²-5x+1)

- distribute -5 to the parentheses:2x+3-5x²+25x-5
- rewrite:-5x²+2x+25x-5+3
- combine like terms:-5x²+27x-2
and
we are done
Twice the number n will be expressed as 2n. So, that will be in our final answer. In order to decrease the number by 6, we will subtract 6. So there will be a - 6 in our final answer. Together, this is 2n - 6, and that is the same as the second option. So, the second option is the correct one.
