Consider these expressions

Expression 1: 3.4(2m - 4)
Expression 2: 4(5.1 - 2.3m)
Expression 3: 2.2(0.16m + 3)

Emma applies the distributive property to simplify the three expressions as shown below she makes a mistake when simplifying one expression

Expression 1: 3.4(2m - 4) = 6.8m - 13.6
Expression 2: 4(5.1 - 2.3m) = 20.4 - 2.3m
Expression 3: 2.2(0.16m + 3) = 0.352m + 6.6

Emma made a mistake in expression
The term is incorrect in Emma’s simplified form of that expression
The term should replace the incorrect term to correctly simplify that expression

Emma made a mistake in expression 1.

The term that is incorrect in Emma's simplified form of that expression is "-13.6."

The correct term should be "-13.6m" in order to correctly simplify that expression.
