Question

(06.07 MC)
Which expressions are equivalent to 3(x + 3y + 2x − y )? (1 point)


3(3x + 2y) and 9x + 6y

3(3x + 4y) and 9x + 12y

3(x + 4y) and 3x + 12y

3(x + 2y) and 3x + 6y

Answer 1

WHY

Answer 2

why? what

Answer 3

I JUST ANSWERED THIS

Answer 4

Can you simplify the given expression.
Combine like terms inside the parentheses.

Answer 5

I'm so confused

Answer 6

hmm...

Answer 7

The answer is the first one because you combine the like terms inside of the parenthesis first, and then you distribute the 3 to that equation.

Answer 8

\(3(\color{red}{x} + \color{green}{3y} + \color{red}{2x} + \color{green}{− y} ) =\)

\(3(\color{red}{x} + \color{red}{2x} + \color{green}{3y} + \color{green}{− y} ) \)

What do you get inside the parentheses?

Answer 9

3 + 2 = 5

Answer 10

2 + 3 = 5

Answer 11

What is x + 2x = ?

Answer 12

What is 3y - y = ?

Answer 13

x + 2 = 3 then 3 - y = 2

Answer 14

There is no x + 2.
Also x + 2 is not 3
It is x + 2x which is equal to 3x.

Answer 15

With the y's it is not 3 - y
It is 3y - y = 2y

Answer 16

That means that when we combine like terms inside the parentheses, we get

3(3x + 2y)

Answer 17

Then we use the distributive property to get

\(3(3x + 2y) = 9x + 6y\)

Answer 18

still dont get it
