Answer 1

Ответ:

4x+(11-8x)=-4x+11

-(7c-5)+4=-7c+9

(5-2b)+(3b-13)=b-8

(5a-33)-(2+4a-3b)=a+3b-35

(1-7y)-(20y-3)-5=-27y-1

(5x-8)-4x-(4-7x)=8x-12

[не понял]

3-15a-12(2a-3)=-39a+39

2a-(a-(a-5))=2a-5

13b-(9b-((c-2b)-7b))=c-

Answer 2

(a+2)² simplifies to (a+2)(a+2) which can be expanded as a² + 2a + 2a + 4. Simplified, it becomes a² + 4a + 4.

(5y-1)² simplifies to (5y-1)(5y-1) which can be expanded as 25y² - 5y - 5y + 1. Simplified, it becomes 25y² - 10y + 1.

(x-4)-(x+4) simplifies to x - 4 - x - 4. Simplified, it becomes -8.

(8m-5)-(8m+5) simplifies to 8m - 5 - 8m - 5. Simplified, it becomes -10.
