Question

(2m + 5) * 2 + 5 * ( m- 2)​

Answer 1

Ответ:

(-2m+m^2-4+2m)-(5+m)

(m^2-4)-(5+m)

m^2-m-9

Answer 2

Ответ:

4m+10+5m-10=9m

Пошаговое объяснение:

4m и 5m складываются,а +10 и -10 уничтожаются

Answer 3

To simplify the expression (2m + 5) * 2 + 5 * (m - 2), you can use the distributive property, also known as the FOIL method (First, Outer, Inner, Last). Here's how you can do it step by step:

1. Start with the expression: (2m + 5) * 2 + 5 * (m - 2)

2. Apply the distributive property to each term inside the parentheses:

   (2m * 2 + 5 * 2) + (5 * m - 5 * 2)

3. Multiply the terms inside each set of parentheses:

   (4m + 10) + (5m - 10)

4. Now, combine like terms. Combine the 'm' terms and the constant terms:

   (4m + 5m) + (10 - 10)

5. Add the 'm' terms and simplify the constants:

   9m + 0

6. Finally, since anything added to 0 is itself, the final simplified expression is:

   9m

So, (2m + 5) * 2 + 5 * (m - 2) simplifies to 9m.
