Step-by-step explanation:
From your problem statement, I believe the equation will look like this:
The slash means "divided by" -- you should use division to solve this equation.
For division involving exponents with the same base, you can use the following rule:
Subtituting for
,
for
and
for
, we get the following:
We are given
We can write it as
we can see that 2y is in first two terms
and -8 is in last two terms
so, we can factor it out
now, we can see that x+4 is common in both terms
so, we can factor it out
we can see that
x+4 is one of factor of terms
so, option-B..........Answer
Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
Where we taking 2 negative because temperature decreases.
Hence, it will take 7 hours for the temperature to reach -19° F.
