Question

-3 (2m -5)-8 (1-6m) -7(3a-2b) +2 (5a+2b)

Answer 1

Ответ:

Пошаговое объяснение:

-3 (2m -5)-8 (1-6m)  = -6m + 15 - 8 + 48m = 42m + 7

-7(3a-2b) +2 (5a+2b) = -21a + 14b + 10a + 4b = -11a + 18b

Answer 2

Ответ: упростить, да?

-6м + 15 - 8 + 48м

42м + 7

-21а + 14b + 10а +4b

11а +28b

Answer 3

It seems like you've provided a mathematical expression that involves variables and constants. To simplify this expression, let's go step by step:

Expression: -3(2m - 5) - 8(1 - 6m) - 7(3a - 2b) + 2(5a + 2b)

1. Distribute the constants and coefficients: -3 * 2m + 3 * 5 - 8 * 1 + 8 * 6m - 7 * 3a + 7 * 2b + 2 * 5a + 2 * 2b

2. Simplify the distributed terms: -6m + 15 - 8 + 48m - 21a + 14b + 10a + 4b

3. Combine like terms: (48m - 6m) + (10a - 21a) + (14b + 4b) + (15 - 8) 42m - 11a + 18b + 7

So, the simplified expression is: 42m - 11a + 18b + 7
