X subtracted from y means y-x
(4x^2-4x+3)-(2x^2-6x-4)
4x^2-4x+3-2x^2+6x+4
4x^2-2x^2-4x+6x+3+4=
2x^2+2x+7
Answer:
The + 78 :- it should be + 60.
Step-by-step explanation:
Long division:-
x - 3 )4x^4 - 6x^3 + 0x^2 + 6x + 3 ( 4x^3 + 6x^2 + 18x + 60 <--- Quotient.
4x^4 - 12x^3
6x^3 + 0x^2
6x^2 - 18x^2
18x^2 + 6x
18x^2 - 54x
60x + 3
60x - 180
183
Let's split it up to make it a little easier.
There's 50 minutes plus another 5 minutes that needs to be added to 11:55
Now, if we add the 5 minutes to 11:55, it becomes 12:00
And we simply have to add the other 50 minutes to 12:00, making it
12:50
So, 55 minutes later than 11:55 is 12:50
Mean Absolute Deviation = 2.5
