Simplify the expression

3n+3(1+8n)
A 11n+1
B 11n+3
C 27n+1
D 27n+3

To simplify the expression 3n+3(1+8n), we first need to apply the distributive property. This means we need to multiply 3 with both 1 and 8n:

3n + 3(1) + 3(8n)

Simplifying further:

3n + 3 + 24n

Combining like terms:

(3n + 24n) + 3

27n + 3

So the simplified expression is 27n + 3. The correct answer is D.
