Simplify: (2.4)(a – 0.2b + 3.5c) options: a.2.4a – 0.48b + 8.4c b. 2.4a – 4.8b + 84c c. 2.4a + 2.2b + 5.9c d. 2.4a – 4.8b + 8.4c

2.4(a - 0,2b + 3,5c)

Make these decimals fractions:

2,4 = 24/10

0,2 = 2/10

3,5 = 35/10

Simplify

24/10 = 12/5

2/10 = 1/5

35/10 = 7/2

Now,

12/5 . (a - b/5 + 7c/2)

Now multiply everything

12/5 . a - 12/5 . b/5 + 12/5 . 7c/2

12a/5 - 12b/25 + 84c/10

Now make the divisions

12/5 = 2,4

12/25 = 4,8

84/10 = 8,4

2,4a - 4,8b + 8,4c

Alternative D.

i think it would be c

mark brainliest if im right

step-by-step explanation:

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
