Question

Г) (b + 0,5);д) (а - 2х);е) (ab - 1).​

Answer 1

Ответ:

г) 0,5(2b+1)

д) ?

е) ?

Объяснение:

г) b+0.5

Для начала преобразуем десятичную дробь в обычную, для этого умножаем 0.5 на 10, получаем $\frac{5}{10}$ , сокращаем до $\frac{1}{2}$

b+$\frac{1}{2}$

Выносим за скобки общий множитель:

$\frac{1}{2}$ * (2b+1) = 0,5(2b+1)

It looks like you have provided a list of expressions with variables. However, some context or specific instructions are missing. It's not entirely clear what you want to do with these expressions. Here are the expressions you've provided:

а) (b + 0.5) д) (а - 2х) е) (ab - 1)

If you could provide more context or specific instructions, I'd be happy to help you further with these expressions. For example, you could specify what you want to do with them, such as simplifying, evaluating, or solving for certain variables. Let me know how I can assist you!
