Answer 2

Ответ:

Пошаговое объяснение:

a) 3,5a+b-5a+4b =-1.5а+5b

в) 7-8n+10n​=7+2n

Answer 3

Let's simplify the given expressions:

A) 3,5a + b - 5a + 4b

First, combine like terms:

3.5a - 5a = (3.5 - 5)a = -1.5a b + 4b = (1 + 4)b = 5b

Now, put it all together:

3.5a + b - 5a + 4b = (-1.5a) + 5b

So, the simplified expression is: -1.5a + 5b

B) 7 - 8n + 10n

First, combine like terms:

-8n + 10n = (-8 + 10)n = 2n

Now, put it all together:

7 - 8n + 10n = 7 + 2n

So, the simplified expression is: 7 + 2n
