Question

4 (5m-3n); -7 (6a-4b); -0,4 (3x+5y-6); -0,4 (3k-2m+10); -11 (5a-4b); 9 (3x-2y):

Answer 1

1) 20m-12n
2) -42a+28b
3) -1,2x-2y+2,4
4) -1.2k+0,8m-4
5) -55a+44b
6) 27x-18y

Answer 2

It looks like you have provided a series of expressions in the form of constants multiplied by algebraic terms. To simplify each expression, perform the indicated multiplication:

1. 4(5m - 3n) = 20m - 12n
2. -7(6a - 4b) = -42a + 28b
3. -0.4(3x + 5y - 6) = -1.2x - 2y + 2.4
4. -0.4(3k - 2m + 10) = -1.2k + 0.8m - 4
5. -11(5a - 4b) = -55a + 44b
6. 9(3x - 2y) = 27x - 18y

These are the simplified expressions for the given terms. If you need any further assistance, feel free to ask!
