You can only add x terms together only if they have the same exponent. For example you can add 2x^2 and x^2 but you cannot add x^2 and x^3.
In this particular problem, you can add 4x^4 and x^4, and x and 8x. So,
<span>
(x + 4x^4) + (x^4 - 2 + 8x)
</span>= 5x^4 + 9x -2
Answer:
d
Step-by-step explanation:
Industries Pollute because of following reasons
- Lack of Policies and Unplanned industrial growth
- Application of obsolete technologies
- Inefficient Waste disposal
As the cost of disposal is high so industries dump their waste in the nearby water bodies which causes water pollution. As industries want to maximize their profit so they neglect the disposal part to increase it.
Proper disposal includes the treatment of waste material to reduce its hazardous nature.

Step-by-step explanation:
When working with parallel lines, it is important to be familiar with their definition and properties. Let’s go ahead and begin with its definition.
Parallel lines are lines that are lying on the same plane but will never meet.
Understanding what parallel lines are can help us find missing angles, solve for unknown values, and even learn what they represent in coordinate geometry.
Since parallel lines are used in different branches of math, we need to master them as early as now.
What are the parallel lines?
Parallel lines are equidistant lines (lines having equal distance from each other) that will never meet.
These are some examples of parallel lines in different directions: horizontally, diagonally, and vertically.
Answer: F = 25.1 kHz
Step-by-step explanation:
Time (period) = 250 × 10^-6 s
Let's first calculate the folding frequency. Given by
NF (rad s-1) = π/Δt
where NF = Nyquist frequency
t = time increment between observations.
The original signal must be filtered by analog or physical methods to remove all frequencies higher than the Nyquist frequency before the signal is sampled or digitized.
F = 3.143/0.00025
F = 12566.37Hz
minimum sampling rate = 2F
2 × 12566.37 = 25132.74Hz
minimum sampling rate = 25.1 KHz
I would THINK it’s 9???? I’m not sure
