Hello from MrBillDoesMath!
Answer:
Choice E and F
Discussion:
From the quadratic formula with a = 3, b = -1, and c = 6
x = ( -b +\- sqrt(b^2 - 4ac) ) / (2a) => substitute in a,b,c from above
x = ( -(-1) +\- sqrt((-1)^2 - 4(3)(6)) / (2*3) => discriminant = 1 - 72 = -71)
x = ( 1 +\- sqrt(-71))/ 6
which are choices E and F
Thank you,
MrB
Answer:
4 feet 2 inches
Step-by-step explanation:
Total Ribbon = 75 feet
Total Students = 18
If equally cut, each student will get the total divided by number of students, that would be:
75/18
That would be:
feet per student
Now, we need the fractional part as inches.
We know 12 inches is 1 feet, so 1/6th feet is:

The fractional part is "2 inches"
Thus,
each piece would be <u>4 feet 2 inches</u>
