Question

1,8*(4-2a)+0,4a-6,2 Плиз

Answer 1

1,8*(4-2а)+0,4а-6,2=7,2-3,6а+0,4а-6,2=1-3,2а

Answer 2

To simplify the expression 1,8*(4-2a)+0,4a-6,2, we can start by distributing the 1.8 to the expression inside the parentheses:

1.8*(4-2a) = 7.2 - 3.6a

Then we can combine this with the second term, 0.4a-6.2:

(7.2 - 3.6a) + (0.4a - 6.2) = 7.2 - 3.2a - 6.2

Finally, we can simplify this expression by combining the constant terms:

7.2 - 3.2a - 6.2 = 1 - 3.2a

Therefore, 1,8*(4-2a)+0,4a-6,2 simplifies to 1 - 3.2a.
