Question

If (x-3)(x+3)=a, then (2x-6)(x+3)=?
2a
3a
4a
6a
9a

Answer 1

isnt it going to be 2a because (2x-6)=> 2(x-3) so u plug it in to (2x-6) than itll be
2(x-3)(x+3) since we know what (x-3)(x+3) is A right? so 2A is correct

Answer 5

I'd also say 2a because if the equation is doubled than the value of a is doubled.
