Answer:
11.8 meter below
Step-by-step explanation:
F(x) = 2x and G(x) = x^2 + 2
(G - F)(x) just means we subtract the functions from each other.
x^2 + 2 - 2x
Let's rearrange the expression
x^2 - 2x + 2
Any multipule of 5 ends with either a 0 or a 5
so we see that ther are no 0's in the list so it must end with 5
so the other 2 digits can be any number
wait, less than 600
so the first digit can be 1 or 3
some possible numbers are
135
175
195
315
375
395
those are the possible numbers
