Answer:
2n+8 or [tex]n^2+8n+16[/tex] if the 2 is an exponent
Step-by-step explanation:
The Distributive property says a(b+c)=ab+ac
Knowing this, lets apply it to the problem...
1) Distribute 2 to n:
2n
2) Distribute 2 to 4:
2n+8
If the problem is squared, use foil (first, outer, inner, last)
(n+4)(n+4)
n^2+4n+4n+16
1) Simplify:
n^2+8n+16
