-4.9t²+7.5t+1.8=2.1
-4.9t²+7.5t-0.3=0
t=-7.5±√(56.25-4*-4.9*-.3)/-2*4.9
t=-7.5±√(44.49/-9.8
t=(-7.5±6.67)/-9.8
t=-.83/-9.8 = .085 or t= -14.17/-9.8 = 1.446

Explanation:
Answer:
2160 inches
Step-by-step explanation:
The actual length of a soccer field is 300 feet. If the width of the field is 180 feet, then what should the width of the scale drawing be in inches?
1 foot = 12 inches
Width of the field = 180 feet
Hence:
1 foot = 12 inches
180 feet = x
x = 180 × 12 inches
x = 2160 inches
Width of the scale drawing in inches = 2160 inches
