For this case we have the following expression:
(x ^ 2 + 2x + 1 / x ^ 2-8x + 16) / (x + 1 / x ^ 2-16)
Rewriting we have:
(((x + 1) (x + 1)) / ((x-4) (x-4))) / (x + 1 / ((x + 4) (x-4)))
Then, we cancel similar terms:
((x + 1) / (x-4)) / (1 / (x + 4))
Rewriting:
((x + 1) (x + 4)) / (x-4)
Answer:
((x + 1) (x + 4)) / (x-4)
Answer:
h= 62 g=118
Step-by-step explanation:
Answer:
77°, 103°
Step-by-step explanation:
x=103°
- z=x=103°
- y=180°-x=180°-103°=77°
-----------
∠5= 42°
∠3= 180°-42°=138°
Answer:
t = 
-------------(1)
The value of t is, 
hour
Step-by-step explanation:
The 1st train travels at 
mph whereas the 2nd train travels at
mph. The trains are headed towards each other. They are s miles apart. In 1 hour their distance is reduced by 
mile
So, in t hour their distance is reduced by 
mile.
Now if the two trains meet after t hour of starting, then,
⇒ t = -------------(1)
If s = 250 unit, = 60 unit and, = 40 unit , then,
from (1), t = (250/(60 + 40)) hour = hour ----(2)
