2(n+4) = (2x_)+(_x4)

Question

Solving for blank, trying to help my daughter and I am not quite clear

Answer 1

Hi Morgan,

 

This problem asks the student to demonstrate the distributive property.

 

2(n+4) = (2 x _)+(_ x 4)  (Adding spaces makes it more readable!)

 

2(n + 4) = 2(n) + 2(4)

 

So the first blank should be filled in with n, and the second blank should be filled in with 2.

 

2(n + 4) = (2 x n) + (2 x 4)

Answer 2

Hi, Morgan.

It looks like your daughter's math class is learning the distributive property.  
It looks like this format:
a(b + c) = a•b + a•c 

Here is an example:
3(m + 7) = 3•m + 3•7

I hope this helps you see what to do for your daughter's problem.
