Question

Do you know any of these three?

Answer 1

2. the ans is C because 3 sides in option C keep the same ratio as the 3            sides of triangle NOP: 7.5/5=1.5, 10.5/7=1.5 and 13.5/9=1.5

3. the ans is D  
    just see from the point Q(16,4), after the first dilation, the x-coordinate of        Q=16*0.25=4, then by subtracting 4 from the x-coordinate of point T (i.e.        -2-4=-6), then you can see only option D has the x-coordinate (x-6), so it        shows that it is the ans

4. i dont know about this.. sorry :(
