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 $54x+18$
