Answer 1

Ответ:

Пошаговое объяснение:

3*(c+5);

3с+15

(k+7)*5;

5к+35

4*(2*k)=8к

6*(3-2*k);

18-12к

3*x+5*(x+7);

3х+5Х+35=8х+35

6*t+2*(t-15)

6t+2t-30

8t-30

Answer 2

It looks like you've provided several mathematical expressions. I can help you simplify these expressions or perform any other operations you'd like. Let's go through each expression one by one:

1. 3*(c+5): This expression can be simplified by distributing the 3 to both terms inside the parentheses: 3c + 35 = 3c + 15

2. (k+7)5: Similarly, distribute the 5 to both terms inside the parentheses: 5k + 5*7 = 5k + 35

3. 4*(2k): Distribute the 4 to the term inside the parentheses: 42k = 8k

4. 6*(3-2k): Distribute the 6 to both terms inside the parentheses: 63 - 6*(2k) = 18 - 12k

5. 3x+5(x+7): Distribute the 5 to both terms inside the second set of parentheses: 3x + 5x + 5*7 = 8x + 35

6. 6t+2(t-15): Distribute the 2 to both terms inside the second set of parentheses: 6t + 2t - 2*15 = 8t - 30

So, I've simplified each expression as requested. If you have any further questions or need additional calculations, please let me know!
