There are two negative roots to the provided polynomial function
f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
We have a polynomial function:
f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2
Using the zero product property:
After solving:
x = -1, x = -0.853, and x = 0.418 (using the graph method)
Thus, there are two negative roots to the provided polynomial function
f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2

Answer:
B. m<B = 65°; m<C = 115°
Step-by-step explanation:
First find the value of x:
3n + 20 = 6n - 25 (opposite bangles if a parallelogram are equal)
Collect like terms
3n - 6n = -20 - 25
-3n = -45
Divide both sides by -3
n = 15
✔️Find angle B:
m<B = 3n + 20
Plug in the value of n
m<B = 3(15) + 20
m<B = 45 + 20
m<B = 65°
✔️Find angle C:
m<C = 180 - m<B (consecutive angles of a parallelogram are supplementary)
m<C = 180 - 65
m<C = 115°
Answer:
x = 360
Step-by-step explanation:
Reorder the terms:
x = 72 + 0.8x
Solving
x = 72 + 0.8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-0.8x' to each side of the equation.
x + -0.8x = 72 + 0.8x + -0.8x
Combine like terms: x + -0.8x = 0.2x
0.2x = 72 + 0.8x + -0.8x
Combine like terms: 0.8x + -0.8x = 0.0
0.2x = 72 + 0.0
0.2x = 72
Divide each side by '0.2'.
x = 360
Simplifying
x = 360
