Question

-(3,3a+1,2b)+(0,7b-1,1b-5,1a)=

Answer 1

Ответ:

-(3,3а + 1,2b) + (0,7b - 1,1b - 5,1a) = -8,4a + 0,8

Пошаговое объяснение:

-(3,3а + 1,2b) + (0,7b - 1,1b - 5,1a) =

-3,3a + 1,2b + 0,7b -1,1b - 5,1a =

(-3,3a - 5,1a) + (0,7b + 1,2b - 1,1b) =

-8,4a + 0,8b

Answer 2

To simplify the expression, let's perform the addition term by term:

For the x-coordinate: 3 + 0 = 3

For the y-coordinate: 3a + 7b - 3 = 3a + 7b - 3

For the z-coordinate: 2b + (-1) + (1b - 5) = 2b - 1 + 1b - 5 = 3b - 6

Therefore, the simplified expression is (3, 3a + 7b - 3, 3b - 6).
