-0.6x(-5+3m-1.4n) розкрити дужки

Answer 1

Ответ:

$- 0.6x( - 5 + 3m - 1.4n) = 3x - 1.8m + 0.84n$

Answer 2

To expand the expression -0.6x(-5+3m-1.4n), we can use the distributive property of multiplication over addition/subtraction.

First, let's simplify the expression within the parentheses (-5+3m-1.4n):

-5 + 3m - 1.4n

Next, we can distribute -0.6 to each term within the parentheses:

-0.6(-5) + (-0.6)(3m) + (-0.6)(-1.4n)

Now, we can simplify each term:

3 + (-1.8m) + 0.84n

Therefore, the expanded expression is:

3 - 1.8m + 0.84n
