D. 3x and 4(x + 1) – x – 4 Choose...

E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...

Step-by-step explanation:

A. 3x + 14 – x + 112 and 4x + 134 Choose...

3x + 14 - x + 112

= 2x + 126

And

4x + 134

Not equivalent

B. 2 + 6x and 2(3x + 1) Choose...

2 + 6x

And

2(3x + 1)

= 6x + 2

Yes, equivalent

C. 3(x + 1) – (1 + x) and 2x + 3 Choose...

3(x + 1) - (1 + x)

3x + 3 - 1 - x

2x + 2

And

2x + 3

No, not equivalent

D. 3x and 4(x + 1) – x – 4 Choose...

3x

And

4(x + 1) - x - 4

= 4x + 4 - x - 4

= 3x

Yes, equivalent

E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...

5.5 + 2.1x + 3.8x - 4.1
