Hannah=h
raoul=r
h=6r
r+h=r+6r=7r=63
r=63/7=9
hannah=6*9=54minutes
If you are just simplifying it it would be 6x because it's 5x plus one more x but if you are trying to find x then I have no idea
4x+5
-4 -4
x+5-4
x=0
0=y
3+5-4
4
I believe this is how the equation is solved
Answer:
Cubic polynomial function with zeros 3,3 and -3 is
Step-by-step explanation:
We need to find a cubic polynomial function with zeros 3,3 and -3.
If zeros of polynomial are: 3,3,and -3
we can write:
x=3, x=3, x=-3
Or
We can write:
x-3=0, x-3=0, x+3=0
Now, we can write them as:
(x-3)(x-3)(x+3)=0
Multiplying the terms, we can find the polynomial:
So, cubic polynomial function with zeros 3,3 and -3 is
