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
