Question

0,2×(3a-2b)-0,4×(6a-7b)

Answer 1

Ответ:

Пошаговое объяснение:

=0,6a-0,4b-2,4a+2,8b=-1,8a+2,4b

Answer 2

0,6a-0,4b-2,4a+2,8b=-1,8a+2,4b

Answer 3

To simplify the expression $0.2 \times (3a - 2b) - 0.4 \times (6a - 7b)$, follow these steps:

1. Distribute the coefficients:

   $0.2 \times 3a = 0.6a$
   $0.2 \times -2b = -0.4b$
   $-0.4 \times 6a = -2.4a$
   $-0.4 \times -7b = 2.8b$

2. Combine like terms:

   $0.6a - 0.4b - 2.4a + 2.8b$

3. Combine $a$ and $b$ terms:

   $-1.8a + 2.4b$

So, $0.2 \times (3a - 2b) - 0.4 \times (6a - 7b) = -1.8a + 2.4b$.
