Circle the equivalent expressions<br> 6x+18-3x-9<br> 6x-3(3x-3)<br> -3(x-3)<br> -6x+3(3+3x)-6x

melamori03 [73]

Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x

Step-by-step explanation:

We have to simplify each expression for comparison

Expression 1:

$6x+18-3x-9\\= 3x+9$

Expression 2:

$6x-3(3x-3)\\= 6x-9x+9\\= -3x+9$

Expression 3:

$-3(x-3)\\= -3x+9$

Expression 4:

$-6x+3(3+3x)-6x\\= -6x+9+9x-6x\\= -3x+9$

Hence,

Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x
