The scale factor is -2. The answer is choice A
------------------------------------------------
How did I get this answer? By picking any pair of preimage and corresponding image points. Let's pick on preimage point A and its paired image value A'.
Note how the x coordinate jumps from -11 to +22. So we multiplied by -2 to do this jump. We can see that 22/(-11) = -2 is another way to get this. Similarly, the same happens to the y coordinates as well: -14/7 = -2.
In short, you multiply the preimage coordinate by the scale factor -2 to get the corresponding image coordinates. Points B and C will follow the same pattern.
Answer:
let ratio be 3x,11xand13x
perimeter=298cm
3x+11x+13x=298
27x=298
x=298/27=11approax
shortest side=3×11=33
Step-by-step explanation:
you are right .

Step-by-step explanation:
a term can be made up of factors. Given your are asked for two, I believe they just want you to factor or the greatest common factor
Answer:
x=2x-5
= -2x=2x-5-2x
= x-2x=-5
