Question

Розкрий дужки 4(a+2) 3(m-5) (4a-6)*9 12(a+b) 5(2m - 3b + 4c) (4x + 5y - 6z) * 14

Answer 1

Ответ:

4а+8

3м-15

36а-54

12а+12б

10м-15б+20с

56х+70у-84z

Answer 2

4(a+2) = 4a + 8 3(m-5) = 3m - 15 (4a-6)*9 = 36a - 54 12(a+b) = 12a + 12b 5(2m-3b+4c) = 10m - 15b + 20c (4x+5y-6z)*14 = 56x + 70y - 84z

Putting it all together: 4a + 8 + 3m - 15 + 36a - 54 + 12a + 12b + 10m - 15b + 20c + 56x + 70y - 84z

Simplify the expression by combining like terms: 52a + 3m + 12b - 15b + 46 + 20c + 56x + 70y - 84z - 54

So, the simplified expression is: 52a + 3m - 3b + 20c + 56x + 70y - 84z - 8
