a
Final size of the picture

b
Number of enlargements

c
Original size of the picture

d
Rate at which the size of the picture increases

Step-by-step explanation:

560

hope this : )

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
