Answer:
You can use the scale factor to determine if a picture is an enlargement if the scale factor is greater than 1. If it is less than 1 like 0.9 then the picture would be a reduction because you would be multiplying the number by a number smaller than 1. Now if we have a scale factor greater than 1 let's say 3. Then the picture would be an enlargement because the number is greater than 1.

Answer:
Infinitely many solutions.
Step-by-step explanation:
12(x+3)=4(2x+9)+4x
12x+36=8x+36+4x
12x+36=12x+36
infinitely many solutions
