так есть решение всеее

Answer 2

Ответ:

1) 3(y+8) = 3*y+3*8 = 3y+24

2) (x-9)*11 = 11*x -11*9 =11x-99

3) 7(5x - 6y+ 7)= 7*5x -7*6y +7*7 =35x-42y+49

Пошаговое объяснение:

Answer 3

1. To simplify the expression 3(y + 8), you can distribute the 3 to both terms inside the parentheses:

3(y + 8) = 3 * y + 3 * 8 = 3y + 24

So, the simplified form of 3(y + 8) is 3y + 24.

2. Similarly, to simplify (x - 9) * 11, distribute the 11 to both terms inside the parentheses:

(x - 9) * 11 = 11 * x - 11 * 9 = 11x - 99

Thus, the simplified expression for (x - 9) * 11 is 11x - 99.

3. Lastly, to simplify 7(5x - 6y + 7), distribute the 7 to each term inside the parentheses:

7(5x - 6y + 7) = 7 * 5x - 7 * 6y + 7 * 7 = 35x - 42y + 49

Therefore, the simplified form of 7(5x - 6y + 7) is 35x - 42y + 49.
