Respuesta :

You should multiply each number inside of the parenthesis by the number outside of the parenthesis. So, multiply 20 by 100 and then 4z and 20. Afterwards, you no longer need the parenthesis around your equation. So, you will be left with 2000 + 80z.
Hello :),
20(100+4z)=20×100+20×4z=2 000+80z
