Given data
1. The mean
2. The median
3. The sample standard deviation

I would say the amount used would be at least 50 gallons because it makes most sense. Hope I helped :))
Solve for x. The multiplicity of a root is the number of times the root appears.
x=-7 (multiplicity of 1)
x=3 (multiplicity of 2)
x=2-i (multiplicity of 1)
x=2+1 (multiplicity of 1)
Answer:
D.300 sq ft , 15 X 20 = 300
