Question

A student attempted to generate an equivalent expression using the distributive property, as shown below:

6(m + 3) = 6m + 3

What was the mistake made?

A. 6 was not multiplied by m
B. Incorrect sign was used for the first term
C. Incorrect sign was used for the second term
D. 6 was not multiplied by 3

Answer 1

the answer is D. 
6 wasnt multiplied by 3. 
the expression should look like this "6m+18"

Answer 2

The Distributive Property: a(b + c) = ab + ac.

To find an equivalent expression to 6(m + 3) using the Distributive Property, multiply 6 by each term inside the parentheses.

6 · m = 6m

6 · 3 = 18

The expression becomes 6m + 18.

The error the student made was not multiplying 6 by 3.

Answer:

6 was not multiplied by 3 (the last option).
