Answer:

12a+2b

Step-by-step explanation:

1. Expand by distributing terms.

20a-8b-2(4a-5b)20a−8b−2(4a−5b)

2. Expand by distributing terms.

20a-8b-(8a-10b)20a−8b−(8a−10b)

 3. Remove parentheses.

20a-8b-8a+10b20a−8b−8a+10b

4.Collect like terms.

(20a-8a)+(-8b+10b)(20a−8a)+(−8b+10b)

5. Simplify.

12a+2b12a+2b

6.Answer

12a+2b

Sharkky
The answer is 12a+2b

That is the answer because:
Following the distributive property
4*5a=20a
4*-2b=-8b
-2*4a=-8a
-2*-5b=10a
So now you have
20a-8b-8a+10a
So combine like terms
12a+2b
