30,840 is expanses for by place value is 30,000 + 800 + 40. Add them together and you get 30,840.
That is 4(-3)^2 + 6(-3) - 5 = 36 - 18 - 5 = 13 Answer
Applying log rules leaves us with the following equation:
x^2 + 8 = 6x
Change to standard form and solve using factoring.
x^2 - 6x + 8 = 0
(x - 4)(x - 2) = 0
x = 4
x = 2
Hope this helps!
