Question

Drag each expression to show whether it is equivalent to 54x plus 18, 18(3x minus 1), or (6 times 9x) plus (6 times 1)

Answer 1

The first option is

`18(3x-1) = 18\cdot 3x - 18\cdot 1 = 54x-18`

The second option is

`6\cdot 9x + 6\cdot 1 = 54x + 6`

So, neither of them is equivalent to
`54x+18`
