Start at 35 and start subtracting 4 (-4) then count each number so (35,31,27,23,19,15,11,7,3,-1) that’s 9 numbers so 1:00Pm +9 hours to 10:00PM and there you go
When exactly do you need the answers? Like have you got them or what?
Answer:
If all three radical expressions can be simplified to have a radicand of 3xy, than each original expression has a radicand that is a product of 3xy and a perfect square.
F(x)=-x^2+9x-18
=-(x^2-9x+18)
=-((x-3)(x-6))
As leading coefficient is negative, between the two zeros is the maximum
=(3+6)/2
=(9)/2
x=4.5
=-(4.5)^2+9(4.5)-18
=2.25
