2)6a-11b 3) -24 +b 4) -7m+28+5m+10=-2m+38

Answer 2

Simplifying the Expressions

Let's simplify each expression step by step:

1) hello_html_2f5f906.gif

The expression "hello_html_2f5f906.gif" does not seem to be a mathematical expression. It appears to be a file name or identifier rather than a mathematical equation. Therefore, it cannot be simplified mathematically.

2) – 12a – 25b + 18a + 14b

To simplify this expression, we can combine like terms. Like terms have the same variables raised to the same powers.

Combining the terms with "a" and the terms with "b" separately, we get:

-12a + 18a - 25b + 14b

Simplifying the "a" terms, we have:

(-12a + 18a) = 6a

Simplifying the "b" terms, we have:

(-25b + 14b) = -11b

Therefore, the simplified expression is:

6a - 11b

3) b – (b + 6) + (b – 18)

To simplify this expression, we can remove the parentheses and combine like terms.

Removing the parentheses, we get:

b - b - 6 + b - 18

Combining the "b" terms, we have:

(b - b + b) = b

Combining the constant terms, we have:

(-6 - 18) = -24

Therefore, the simplified expression is:

b - 24

4) – 7(m – 4) + 5(m + 2)

To simplify this expression, we can remove the parentheses and combine like terms.

Removing the parentheses, we get:

-7m + 28 + 5m + 10

Combining the "m" terms, we have:

(-7m + 5m) = -2m

Combining the constant terms, we have:

(28 + 10) = 38

Therefore, the simplified expression is:

-2m + 38
