In 4 hours if you count the miles by the road linking the 2 buses. This is because 55 for one bus and 45 for the other bus added together equals 100 miles/hour. Therefore, 4 hours will be the time the 2 buses are 400 miles apart.
Answer:
C
Step-by-step explanation:
Using the square root and the given trinomial what is the answer to this hard problem
Easy peasy
a circle centered at the origin is form
x^2+y^2=r^2
r=radius
point (5,-12) is on it
sub to find r^2
(x,y)
(5,-12)
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
sqrt both sides
13=r
the radius is 13
answer is not listed
10 + -4 = 6
10 * -4 = -40
Use the factors of forty.
