Answer:
I think it's A
Step-by-step explanation:
sqrt 7 ( sqrt 14 + sqrt 3 )
distribute
sqrt(7) sqrt(14) +sqrt(7) *sqrt(3)
sqrt(98) + sqrt(21)
sqrt(49*2) + sqrt(21)
sqrt(49) * sqrt(2) + sqrt(21)
7sqrt(2) + sqrt(21)
17-
Quotient: 6x+2
Remainder: 20/x^2+3 (20 over x to the power of 2 plus 3)
18-
Quotient: x^2+3 (x to the power of 2 plus 3)
Remainder: 6/4x^2+2 (6 over 4 x to the power of 2 plus 2)
Time is -b/2a, which is 3.
f(3) = 24 = maximum congestion
