Question

1,5(2,5x+4.2)-2.4(4.2-5.6x)

Answer 1

Ответ:

1,5(2,5х+4,2)-2,4(4,2-5,6х)=3,75х+6,3-10,08+13,44х=17,19х-3,78.

Answer 2

To simplify the expression 1.5(2.5x + 4.2) - 2.4(4.2 - 5.6x), you can use the distributive property and then combine like terms:

1.5(2.5x + 4.2) - 2.4(4.2 - 5.6x)

First, distribute 1.5 and -2.4 to the terms inside the parentheses:

= 3.75x + 6.3 - 10.08 + 13.44x

Now, combine like terms:

= (3.75x + 13.44x) + (6.3 - 10.08)

= 17.19x - 3.78

So, the simplified expression is 17.19x - 3.78.
