Josh wants to simplify the expression (-8)(10+(-5)+(-8))

The error make by Josh is none .

Step-by-step explanation:

Given as :

The actual expression is written as ( - 20 a - 8 - 12 b )

The expression written by Josh as - 4 ( 5 a + 2 + 3 b )

Now, From the actual expression , if we take the common term

Then - 4 ( 5 a + 2 + 3 b )

The actual expression after taking common term 4 , is written as  

- 4 ( 5 a + 2 + 3 b )

And The expression written by Josh is also  - 4 ( 5 a + 2 + 3 b ) , which is the similar one.

So, no error makes by Josh

Hence The error make by Josh is none . Answer
