Question

Раскрой скобки и приведи подобные 1)-3d -(8p-3d) 2)(2+3а)+(7а-2) 3) а-(а-(2а-4)

Answer 1

Ответ:

1)-3d- 8p+ 3d= -6d -8p

2)2+3a+7a-2= 4+10a

3)a(a- 2a+4)= a - (4- a)= a - 4+ a= 2a-4

Answer 2

1. -3d - (8p - 3d) = -3d - 8p + 3d Simplifying, we can cancel out the -3d and +3d terms: = -8p

2. (2 + 3a) + (7a - 2) = 2 + 3a + 7a - 2 Simplifying, we can combine the like terms 3a and 7a: = 10a

3. a - (a - (2a - 4)) = a - a + 2a - 4 Simplifying, we can cancel out the a and -a terms: = 2a - 4
