Question

Lisa says that the expressions 8x - 6x + 8 and 2(x + 4) are not equivalent because one expression has a term that is subtracted and the other does not. Do you agree?explain.Will send image.

Answer 1

No, the expression are equivalent. The first option, 8x - 6x + 8, can be simplified to 2(x+4), which equals 2(x+4)

Explanation:

The first thing is to confirm if the expressions are equivalent or not

`\begin{gathered} 8x-6x+8=2(x+4) \\ 2x+8=2(x+4) \\ 2(x+4)=2(x+4) \end{gathered}`

Therefore:

No, the expression are equivalent. The first option, 8x - 6x + 8, can be simplified to 2(x+4), which equals 2(x+4)
