Answer:
x = 5
Step-by-step explanation:
1. Expand
8x - 5x + 5 = 20
2. Simplify
3x + 5 = 20
3. Subtract 5 from both sides
3x = 20 - 5
4. Simplify
3x = 15
5. Divide both sides by 3
x = 15/3
6. Simplify
x = 5
Answer:
10x^8 is the sum
Step-by-step explanation:
Answer:
The answer is "false".
Step-by-step explanation:
The following are the description of the line, line segment, and ray.
- Line: The line is a single-dimensional figure, which has a length but no width. It has the direct path of points, which runs to the next without stopping in both directions.
- Line Segment: It is the portion of a line is called a segment. It has two end-points, which includes the endpoints for all the positions between these. The length of this section, can't be determined.
- Ray: The ray would be a straight path for one destination and moves one way.
Descares Theorem says that the number of roots of a polynomial is equal to its highest exponent, and the roots could be real and/or imaginary (complex).
However is their is one complex root (a + i.b), it's conjugate is also
a root (a-i.b).
In the equation x⁴ - 4x³ - 2x² + 12x + 9 = 0, we have already 3 roots, then the 4rth cannot be a complex one since we don't have a fifth for its conjugate.
