Question

7с-6 (5+с) упростить выражение

Answer 1

7с-6(5+с)=7с-30+6с=13с-30

Answer 2

To simplify the expression, you can apply the distributive property, which states that a(b + c) = ab + ac.

Let's simplify the expression step by step:

1. Distribute the 7c across the terms inside the parentheses: 7c - 6(5 + c)

2. Multiply -6 by each term inside the parentheses: 7c - 6 * 5 - 6 * c

3. Simplify the multiplication: 7c - 30 - 6c

Now, since both terms have "c" as a common factor, we can combine them:

4. Combine the "c" terms: (7c - 6c) - 30

5. Perform the subtraction: 1c - 30

6. Finally, the simplified expression is: c - 30
