Answer:
Options (C) and (F)
Step-by-step explanation:
Polynomial function is,
f(x) = x³ - x² - 5x - 3
Possible rational roots of the given function will be =
By putting x = -1
f(-1) = (-1)³ - (-1)² -5(-1) - 3
= -1 - 1 + 5 - 3
= 0
Therefore, x = -1 will a root of the given function.
Now we apply synthetic division to get the other roots,
-1 | 1 -1 -5 -3
<u> ↓ -1 2 3 </u>
1 -2 -3 0
Therefore, factored form of the polynomial will be (x + 1)(x² - 2x - 3).
Now we will find the roots of (x² -2x - 3).
x² - 2x - 3 = x² - 3x + x - 3
= x(x - 3) + 1(x - 3)
= (x + 1)(x - 3)
For roots of the function, f(x) = 0
(x + 1)(x - 3) = 0
x = -1, 3
Therefore, roots of the function are x = -1, 3
Options (C) and (F) are the answers.
Answer:
54 is the volume
Step-by-step explanation:
Multiply 9 * 2 * 3 = 54
In math, the associative and commutative properties are laws applied to addition and multiplication that always exist. The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.
Answer:
Answer C
−5x3 + 4x2 − 5x; is a polynomial
Step-by-step explanation:
you just use distributive property to simplify, and then you know the closure property demonstrates that when you are adding, subtracting, multiplying, or dividing two polynomials, they will remain polynomials.
pls mark branliest
since all angles are the same, then the sides must also be the same measure
therefore
6x-3=3x+6=5x
we can solve for x by taking any 2 equations
6x-3=5x
minus 5x both sides
x-3=0
x=3
