Option 1,2,5 and 7 are correct.

Step-by-step explanation:

To find : Which of the following expressions are equivalent to the expression 4x + 8?

Solution :

We solve every given options,

1) $4(x+2)$

$4(x+2)=4x+8$

It is equivalent.

2) $6x+8-2x$

$6x+8-2x=4x+8$

It is equivalent.

3) $4x+2$

It is not equivalent.

4) $2(2x+8)$

$4x+16$

It is not equivalent.

5) $3x+9+x-1$

$3x+9+x-1=4x+8$

It is equivalent.

6) $4(x+8)$

$4(x+8)=4x+32$

It is not equivalent.

7) $2(2x+4)$

$2(2x+4)=4x+8$

It is equivalent.

Therefore, Option 1,2,5 and 7 are correct.

Step-by-step explanation:

4x+8

6x+8-2x=4x+8 yes

4(x+8)=4x+32 no

2(2x+4)=4x+8 yes

4x+2 no

Answers: 6x+8-2x( first choice) , 2(2x+4) ( third choice)

2(2x+4)

Step-by-step explanation:

For an expression to be equivalent it must simplify to 4x + 8.

6x+8−2x   = 4x + 8 YES

4(x+2)  = 4x + 8 YES

4x+2  = 4x + 2 NO

2(2x+8)  = 4x + 16 NO

4(x+8)  = 4x + 32 NO

3x+9+x−1  = 4x + 8 YES

2(2x+4)  = 4x + 8 YES
