HELP ME ? ILL MEDAL AND FAN

Which of the following is equivalent to the expression below?

(9 + 2x) - 2x

A. 9
B. 9 + 4x
C. 9 - 4x
D. 2

Answer 1

In the given expression, the parentheses are not needed, so just drop them.
Then, combine like terms.

Answer 2

no A

Answer 3

its A

Answer 4

No. First, just drop the parentheses.
You get
\(9+ 2x - 2x\)
Now look at 2x - 2x.
They are like terms.
If you subtract something (2x) from itself (2x) you get zero.
Just like 10 - 10 = 0, 5 - 5 = 0, x - x = 0, also 2x - 2x = 0.
That means the 2x - 2x part is zero, and you are just left with 9.

Here is how this porblem looks like step by step:

\((9 + 2x) - 2x\)

\(= 9 + 2x - 2x \)

\(= 9 + 0\)

\(=9\)
