Answer:
They cost the same amount
Step-by-step explanation:
Given
Lin: where x = 14
Max: for 14 days
Required
Which is less expensive?
Max charges has been given from the question as; $120 for 14 days.
To determine Lin's, we simply substitute 14 for x in
The above result of y shows that Max charges for 14 days is also $120.
<em>Hence, they (Lin and Max) cost the same because they both equal to $120 for 14 days</em>
As finding joint solution
Try taking it one step at a time and multiplying each set one by one. watch the negative signs! remember: a negative times a positive is negative, and a negative times a negative is positive!
-2m(m+n-4)= -2m^2 -2mn+8m
next:
5(-2m+2n) = -10m+10n
next:
n(m+4n-5) = nm + 4n^2-5n
you're left with
-2m^2-2mn+8m-10m+10n+nm+4n^2-5n
now, add "like terms" (aka terms that have the same letters and powers, like 10n and -5n)
So,
-2m^2-nm-2m+5n+4n^2
is your answer! (answer choice C.)
Answer:
the
answer is 29.255... i think
Step-by-step explanation:
you just add all the numbers
Answer:
<u>a = - 5.</u>
Step-by-step explanation:
The given equation is,
- Negative (5 minus (a + 1)) = 9 minus (5 minus (2a minus 3))
We need to change it to its numerical form ⟶ - (5 - (a + 1)) = 9 - (5 - (2a - 3))
Now, by solving it...
