Answer:
Step-by-step explanation:
A third degree polynomial has a <em>total of three roots</em>, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
The first one is correct.
There is a VERY simple way you can do this
Here is how.
It's called the "Butterfly Method" (IDK if anyone calls it that, but I do!)
So basically, you look at the numerator for one of your numbers, and the denominator of the other number, and you multiply them! So...
1/7, you would take the seven...
1/4, and multiply it by the one...
so 7×1
and you get seven!
Then you do...
1/7, take the one...
1/4, take the four...
so 1×4
and you get four!
Whichever one is bigger (or smaller, but only if you are trying to find out which fraction is smaller...) is your answer!
Hope this helped!!!!!!!!!!!!!!
Answer:
12sweet
Alex's ratio=3
Thomas' ratio =2
I.e 3+2=5
Sweet=30
Thomas' share=2/5*30
=12
I.e Thomas' share is equal to 12 sweets
Answer:
63=7 80=8 52=7 112=10 864=29 396=19 800=28 7200=84
Step-by-step explanation:
now all you have to do is find factors which shouldn't be that hard
Graph plots and see where is curves
