Answer:

Option B.

Step-by-step explanation:

The given expression is

5p+3p+(-9)

We need to find an expression which is equivalent to the given expression.

Combine like terms.

(5p+3p)-9

8p-9

The simplified form of given expression is 8p-9. So, option A is incorrect.

In option B, the given expression

3(p+(-3))+5p

3(p-3)+5p

Using distributive property, we get

3p-9+5p

Combined liker terms.

(5p+3p)-9

8p-9

It is same as the simplified form of given expression.

Therefore, the expression 3(p+(-3))+5p is equivalent to the given expression and correct option is B.
