Ответ:

Пошаговое объяснение:

1)9x+4(15-8x)  = 9x + 60 - 32x = -23x + 60

2)-3(2p-1)+4  = -6p + 3 + 4 = -6p + 7

3)21x-7-4(9x+3)  = 21x - 7 - 36x - 12 = -15x - 19

4)33-8(11b-1)-2b = 33 - 88b + 8 - 2b = 41 - 90b

Answer 3

Let's simplify the given expressions:

1. 9x + 4(15 - 8x) = 9x + 4(15) - 4(8x) = 9x + 60 - 32x = -23x + 60

2. -3(2p - 1) + 4 = -6p + 3 + 4 = -6p + 7

3. 21x - 7 - 4(9x + 3) = 21x - 7 - 36x - 12 = -15x - 19

4. 33 - 8(11b - 1) - 2b = 33 - 88b + 8 - 2b = -90b + 41

So, the simplified expressions are:

1. -23x + 60
2. -6p + 7
3. -15x - 19
4. -90b + 41
