Question

0,3(2x-6) +0, 4(3x+1)​

Answer 1

0,3 (2x - 6) + 0,4 (3x + 1) = 0,6х - 1,8 + 1,2х + 0,4 = 0,6х + 1,2х - 1,8 + 0,4 = 1,8х - 1,4.

Answer 2

To simplify the expression 0.3(2x - 6) + 0.4(3x + 1), you can distribute the constants (0.3 and 0.4) to the terms inside the parentheses and then combine like terms:

0.3(2x - 6) + 0.4(3x + 1)

= (0.3 * 2x - 0.3 * 6) + (0.4 * 3x + 0.4 * 1)

Now, perform the multiplications:

= (0.6x - 1.8) + (1.2x + 0.4)

Next, combine like terms:

(0.6x + 1.2x) + (-1.8 + 0.4)

= 1.8x - 1.4

So, the simplified expression is 1.8x - 1.4.
