Question

Which expressions are equivalent to 3(x + 3y + 2x − y )?
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

The two equivalent expressions are 3(3x+2y) and 9x+6y.
To get these answers, first simply the expressions within the brackets to give 3(3x+2y). Then expand for 9x+6y.

Answer 2

The expression 3(x + 3y + 2x − y ) is equivalent to 3(3x + 2y) and 9x + 6y option (A) is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

= 3(x + 3y + 2x − y)

Adding like terms:

= 3(3x + 2y)

Using the distributive property:

= 9x + 6y

Thus, the expression 3(x + 3y + 2x − y ) is equivalent to 3(3x + 2y) and 9x + 6y option (A) is correct.
