They will see each other every 30 days but won't every 15 days
X2 - 16, is the answer. The first one.
x^2 - 16 = (x)^2 - 4^2, difference of two squares :)
K=10
Here is the equation
180-115=65
(4K+5)+(6k+10)+65=180
93 / 12 = 7.75
so Lester earns $7.75 a hour.
if he earns $62 how many hours did he work.
so 62 = 7.75 (h)
62/ 7.75 = 8
so he worked 8 hours.
If e is between them, then the distances DE and EF add to the total, DF. So the answer is just 27 + 34 which is 61, A
