1 → B
multiply each term in the parenthesis by the 6 outside
6(b-7) = 6b - 42
2 → D
multiply each term in the parenthesis by the 3 outside
3(4x+6y+2) = 12x+18y+6
3 → A
the value outside the parenthesis is -1, hence each term inside is multiplied by -1
-1(6x+5y) = -6x -5y

Step-by-step explanation:
3x + (2x + 4) is equivalent to (3x + 2x) + 4
because there is no change of signs taking place as there is no (-) sign in front of the brackets
3x + (2x + 4) | (3x + 2x) + 4
3x + 2x + 4 | 3x + 2x +4
5x + 4 | 5x + 4
