F(x)=x^5 + 5*x^4 - 5*x^3 - 25*x^2 + 4*x + 20
By examining the coefficients of the polynomial, we find that
1+5-5-25+4+20=0 => (x-1) is a factor
Now, reverse the sign of coefficients of odd powers,
-1+5+5-25-4+20=0 => (x+1) is a factor
By the rational roots theorem, we can continue to try x=2, or factor x-2=0
2^5+5(2^4)-5(2^3)-25(2^2)+4(2)+20=0
and similarly f(-2)=0
So we have found four of the 5 real roots.
The remainder can be found by synthetic division as x=-5

I hope I helped have an amazingg day
Answer:
C
Step-by-step explanation:
Let's break down the definitions.
Supplementary = degrees add up to 180
Vertical = share a common vertex
Complementary = degrees add up to 90
Adjacent = share a common side and vertex
Since the degrees add up to 90 and don't share a common side/vertex, the angles are complementary.
Answer:
Step-by-step explanation:
5 - (x + 5) > -2(x + 4)
5 - x - 5 > -2x - 8
-x > -2x - 8
-x + 2x > -8
x > -8
