Answer:
3hours and 30 minutes moving and 2 and a half hours stationary
Step-by-step explanation:
1 hour + 30 minutes + 1 hour + 30 minutes + 30 minutes for moving
1 hour + 1 hour + 30 minutes for stationary.
Since triangle BDE is right, we can check it for special rules: BD is hypotenuse = 20, and BE = 12, both divisible by 4: get 5 and 3... so it's a 3-4-5 special right triangle, the 4×4 = 16 m for side DE.
Since AD bisects angle A, I think then side DG should be congruent with DG. So then
DG = 16 m
Hello from MrBillDoesMath!
Answer:
Binomial with a degree of 6 (the second Choice)
Discussion:
(a^3b+9a^2b^2-4ab^5) - (a^3b-3a^2b^2+ab^5) =
(-4ab^5- ab^5) + ( a^3b-a^3b) + ( 9a^2b^2 + 3a^2b^2) =
(-4ab^5- ab^5) + 0 + ( 9a^2b^2 + 3a^2b^2) =
12 a^2 b^2 - 5 a b^5
This is a binomial with degree 6 (degree of last term = 1 + 5 = 6).
Thank you,
MrB
