Josh is trying to factor the expression -20a - 8 - 12b. he writes -4(5a + 2 + 3b). what error did josh likely make?

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

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

1696 hundred thousand
