I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)
Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original<span />
If the scale factor is less then 1, it was reduced.
If the scale factor is more than 1, it was enlarged.
If it is equal to 1, it is the same.
Hope this helps!
Question 14 is B and C
Question 15 is D
Question 16 is A
And question 18 is B and D
