Question

Розкрийте дужки: 1)-с*(2,7-1,2d)= 2) 1,6*(2n+m)= 3)(n-m)*(-2,4p)=

Answer 1

Ответ:

1) -c•(2,7-1,2d) = -2,7c + 1,2cd

2) 1,6•(2n+m) = 3,2n + 1,6m

3) (n-m)•(-2,4p) = -2,4np + 2,4mp

Answer 2

Ответ:

1) -2,7с+1,2сd

2) 3,2n+1,6m

3) -2,4np+2,4mp

Answer 3

1. -с*(2,7-1,2d) can be simplified as follows: -с*(2,7-1,2d) = -с2,7 + с1,2d = -2,7с + 1,2cd

2. 1,6*(2n+m) can be simplified as follows: 1,6*(2n+m) = 1,62n + 1,6m = 3,2n + 1,6m

3. (n-m)(-2,4p) can be simplified as follows: (n-m)(-2,4p) = -2,4pn + 2,4pm
