Answer 1

Ответ:

-13d-2c

Объяснение:

6,5d-1,5(4c+5d)+4(c-3d)= (открываем скобки)6,5d-6c-7,5d+4c-12d= (складываем)-13d-2c

Answer 2

It seems like you've provided a mathematical expression:

6.5d - 1.5(4c + 5d) + 4(c - 3d)

Let's simplify this expression step by step:

1. Distribute the -1.5 and 4 through the parentheses: 6.5d - 6c - 7.5d + 4c - 12d

2. Combine like terms: (6.5d - 7.5d - 12d) + (-6c + 4c) -13d - 2c

So, the simplified expression is -13d - 2c.
