Пошаговое объяснение:

1) -7,2m

2)ab

3) -6a + 48

4) -0,4b +2c

Answer 2

1) 8m • (-0,9)= -7,2m

2) -0,2 a •( - 5b)=ab

1) - 6 • (a-8) = -6a+48 = 48-6a

2) 4 • (-0,1 b+0,5c) = -0,4b+2c=2c-0,4b

Answer 3

It looks like you have a set of mathematical expressions, and it seems like you'd like me to simplify them. Let's go through each expression one by one:

1. 8m * (-0.9): Multiplying 8m by -0.9 gives you -7.2m.

2. -0.2a * (-5b): Multiplying -0.2a by -5b gives you 1ab or simply ab.

3. -6 * (a - 8): To simplify this expression, distribute the -6 to both terms inside the parentheses: -6 * a + 6 * 8 This simplifies to -6a + 48.

4. 4 * (-0.1b + 0.5c): To simplify this expression, distribute the 4 to both terms inside the parentheses: 4 * (-0.1b) + 4 * 0.5c This simplifies to -0.4b + 2c.

So, the simplified expressions are:

1. -7.2m
2. ab
3. -6a + 48
4. -0.4b + 2c
