Answer 1

Ответ:

1)2a-21

2)-3x+4

3)19

4)-6x-a

5)ax-c

Answer 2

A) Let's simplify each expression:

1. 2*(a - 9) - 3 Distribute the multiplication: 2a - 29 - 3 Simplify: 2a - 18 - 3 Combine like terms: 2a - 21

2. -3*(x + 2) + 10 Distribute the multiplication: -3x - 32 + 10 Simplify: -3x - 6 + 10 Combine like terms: -3x + 4

B) Let's simplify the expression:

5*(4 - x) - (-5x + 1) Distribute the multiplication: 54 - 5x - (-5x) - 1 Simplify: 20 - 5x + 5x - 1 Combine like terms: 20 - 1 Result: 19

r) Let's simplify the expression:

-3*(2x + 5) + (15 - a) Distribute the multiplication: -32x - 35 + 15 - a Simplify: -6x - 15 + 15 - a Combine like terms: -6*x - a Result: -6x - a

A) Let's simplify the expression:

x*(a - b) - (c - bx) Distribute the multiplication: xa - xb - c + bx Rearrange terms: xa + bx - x*b - c Combine like terms: (a + b)*x - (c + b)

So, the simplified expression is (a + b)*x - (c + b).
