Answer 1

4a-3b+c
-m-2n-k
0.19+4a+c
x+8y-z
m+9n-k-p
a-4b-3c+d

Answer 2

Mathematical Expression Expansion

To expand the given mathematical expression and simplify it, we will start by removing the parentheses and then combining like terms.

1) Start by expanding the expression: - 4a - (3b - c) + 2 - -m - (2n + k) + 3 - 0.19 + (4a - c) - x + (8y - z) - m + (9n - k - p) - a - (4b + 3c - d)

2) Now, let's remove the parentheses and combine like terms.

Expanded and Simplified Expression

The expanded and simplified expression is as follows:

- 4a - 3b + c + 2 - m - 2n - k + 3 + 0.19 + 4a - c + x + 8y - z + m + 9n - k - p + a - 4b - 3c + d

- Combining like terms: - 9a - 7b - 2c + x + 8y - z + 2m + 6n - 2k - p + a + d + 5.19

So, the expanded and simplified expression is 9a - 7b - 2c + x + 8y - z + 2m + 6n - 2k - p + a + d + 5.19.
