Answer:
Step-by-step explanation:
There isn't one. The first term is x^4.
The other two are stated in terms of k. There is nothing common here.
You can do 2 of the three. Terms 2 and 3 have a common factor of 4k, so what you can get is
x^4 - 4k(k^2 - 1)
1 meter is 3.3 ft.....so 70 meters is (70 * 3.3) = 231 ft.....so ft per second is 231 ft per second
at 2 seconds.....231 * 2 = 462 ft
Ordered pair is
<u>Step-by-step explanation:</u>
We have the following inequalities:
and
. In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !
and ,
which implies:
⇒
⇒
⇒ 
putting value of x in both inequalities we get,
and 
and 
and 
Hence at x =
and y =
above inequalities are satisfied. ∴ Ordered pair is

Answer:
$9,840
Step-by-step explanation:
Let the money earned from college be 'x'.
Given:
Total money earned from the two jobs = $50,450
Money earned at the store = 1250 + 4(Money earned at college)
∴ Money earned at the store = 
Now, total money earned by Erica is the sum of money earned at store and college. Therefore,
Total money = Money at store + Money at college

Therefore, the money earned by Erica from her job at the college is $9,840.
