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

choose all the expressions that are equivalent.

6x+8−2x

4(x+2)

4x+2

2(2x+8)

4(x+8)

3x+9+x−1

2(2x+4)

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) [tex]4(x+2)[/tex]

[tex]4(x+2)=4x+8[/tex]

It is equivalent.

2) [tex]6x+8-2x[/tex]

[tex]6x+8-2x=4x+8[/tex]

It is equivalent.

3) [tex]4x+2[/tex]

It is not equivalent.

4) [tex]2(2x+8)[/tex]

[tex]4x+16[/tex]

It is not equivalent.

5) [tex]3x+9+x-1[/tex]

[tex]3x+9+x-1=4x+8[/tex]

It is equivalent.

6) [tex]4(x+8)[/tex]

[tex]4(x+8)=4x+32[/tex]

It is not equivalent.

7) [tex]2(2x+4)[/tex]

[tex]2(2x+4)=4x+8[/tex]

It is equivalent.

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

6x+8-2x

2(2x+4)

4(x+2)

3x+9+x-1

Hope this helps!

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)

It’s all of those except 2(2x+8) , 4c+2 , & 4(x+8)

6x+8−2x

4(x+2)

3x+9+x−1

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
