He arrives at 9:30 because if you take 8:40 (when dealing with time I like to think of it as a whole number so 8:40 would become 840) then just add 50 minutes to 8:40 (or 840+50 which equals 890 also know as 9:30 because you have to subtract 60 from 90 (because 60 is the limit in time (well technically 59 is)) then add one to 8 like so, which equals 9:30 Enjoy!=)

Answer:
The simplified version is P^21
Answer:
Area = L^2 + 5L units^2
Step-by-step explanation:
Length = L
Width = L + 5 Because it is 4 longer than the length.
Area = W * L
Area = L * (L + 5)
Area = L^2 + 5L units^2
You can test it by substituting number in:
If the length is 4 and the width is 9 (4 + 5)
4 * 9 = 36 units^2
4^2 + 5 * 4 = 16 + 20 = 36 units^2

just insert your points into it:
a: 2*2-3*-4<=-10?
4+12<=-10? no
b: 2*3-3*1<=-10?
6-3<=-10? no
c: 2*-4-3*2<=-10?
-8-6<=-10?
yes c is a solution: -14<=-10
d: 2*4-3*4<=-10?
8-12<=-10? no
