The actual width ( w) of a regulation soccer field is 90 meters (m), and the actual length is 120 meters (m). a coach has drawn a scale model of the field on a blackboard. if the longest side of his drawing is 18 cm, how long is the other side of the drawing( w)?

Which is the scale factor proportion for the enlargement shown?

If on=8x-8,lm=7x+4,nm=x-5,and ol=3y-6
