Question

0.4×(2+а)-1.5×(а-6)

Answer 1

Ответ:0.8+0.4а-1.5а+9=9.8-1.1а

Answer 2

To simplify the expression, let's solve it step by step:

1. Start with the given expression: 0.4 × (2 + а) - 1.5 × (а - 6)

2. Distribute the multiplication:

0.4 × 2 + 0.4 × а - 1.5 × а + 1.5 × 6

3. Simplify the terms:

0.8 + 0.4а - 1.5а + 9

4. Combine like terms:

(0.4а - 1.5а) + (0.8 + 9)

Now, combine the coefficients of 'а':

-1.1а + 9.8

So, the simplified expression is: -1.1а + 9.8
