Answer:
I believe it is e.
Step-by-step explanation:
2/5 equals 0.4, which is the same as 0.40
Answer:
1. zeros of polynomials -- x-values for which the value of the polynomial is zero
2. quartic polynomial -- fourth degree (polynomial)
3. irreducible -- cannot be factored
4. leading coefficient -- coefficient of the term with the highest power
5. end behavior -- the direction of a graph for very large positive and negative values of x
6. leading term -- the term in a polynomial with the highest power
7. cubic polynomial -- third degree (polynomial)
Step-by-step explanation:
These are definitions. They need no explanation.
Width = x
length = 3x + 4
x + x + 3x + 4 + 3x + 4 = 60
add
8x + 8 = 60
subtract
8x = 52
x = 6.5
width = 6.5
length = 23.5
Answer:
x^4 -x^3 -9x^2 -11x -4
Step-by-step explanation:
We can use the zero product property
(x-a) (x-b) (x-c) (x-d) where a b c d are the roots
(x- -1)(x- -1)(x- -1) ( x-4) since the root -1 is repeated 3 times and 4 is a root
(x+1)(x+1)(x+1) ( x-4)
Foil the first two terms and the last two terms
(x^2 + 2x+1)( x^2 -3x-4)
Foil again
x^4 -3x^3 -4x^2 +2x^3 -6x^2 -8x +x^2 -3x-4
Combine like terms
x^4 -x^3 -9x^2 -11x -4
