Which expression is equivalent to 3n+2(1-4n)? a) 2-n
b) 2-5n
c) 2+11n
d) 2-11n
Samuel chose A as his answer. Explain why he did that.

He only multiplied the 2 to the first term in the parentheses instead of both terms

Step-by-step explanation:

3n+2(1-4n)

Distribute

3n + 2 -8n

Combine like terms

2 -5n

Samuel made the mistake of incompletely distributing

He only multiplied the 2 to the first term in the parentheses instead of both terms

3n+2(1-4n)

3n +2 -4n

2-n

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
