**Answer:**

B. All real numbers

**Step-by-step explanation:**

2(x + 1) = 2x + 2

Distribute the 2 inside the parenthesis.

2x + 2 = 2x + 2

Since the two expressions are equal and will stay equal with any value, the answer to this question is **All real numbers.**

Example:

2(x + 1) = 2x + 2

2(5 + 1) = 2(5) + 2

2(6) = 10 + 2

12 = 12

2(x + 1) = 2x + 2

2(150 + 1) = 2(150) + 2

2(151) = 300 + 2

302 = 302

The expression is equal for any value put in x.

Sorry I’m late.

Remember:

A STATISTICAL QUESTION has variable answers.

Ex: How many toys are in the U.S?

A NON-STATISTICAL QUESTIONS have only one answer

1/x+1/a=1/a

minus 1/a from both sides

1/x=0

false

let's try a differnt way

1/x+1/a=1/a

times both sides by xa

a+x=x

minus x from both sides

a=0

???

1/0 is undefined

this creates problems

no solution
