Answer:
the first one in the picture
Step-by-step explanation:
8x8x8x8=4096
9x9x9x9=6561
4096x6561=26873856
72x72x72x72=26873856
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0
y^2-3y=0
y(y-3)=0
y1=0 -----------y2=3

i'll try my best to help !!
The scale 1:35 indicates that for every 1 meter on the scale model, there are really 35 meters in real life.
So if the scale model is 6.6 meters, you would do 35 * 6.6 to find the length in real life, which is 231 meters.
The answer is 231 meters.
