Question

Jamie says that the expression s6x-2x+4 and 4(x+1)are not equivalent because one expression has a term that is subtracted and the other does not. Do you agree? Explain

Answer 1

No Jamie is incorrect

Explanation:

No, because in the expression 4(x+1) you will first need to multiply 4 by x, your result is 4x, and then you multiply 4 by 1, you get 4, so the answer will be 4x+4.

Also in the expression 6x-2x+4 ,you will first need to subtract 2x from 6x, your result is 4x ,and then you add 4 , so the answer will be 4x + 4

Our final answer is:

6x-2x+4 = 4x + 4 and 4(x+1) = 4x + 4

Answer 2

I do not agree. When the expressions have like terms collected and are factored, they are the same.

Explanation:

Make 6x-2x+4 the same as 4(x+1):

6x - 2x + 4 Collect the like terms 6x and -2x

= 4x + 4 Factor. Divide each term by 4 and take it out of a bracket

= 4(x + 1)

4(x+1) = 4(x+1)

They are equivalent expressions, just written differently.
