<span>The Z transform is related to Laplace transform and is applied to analyze digital circuits. The Fourier transform, on the other hand, is a type z-transform, i.e z-transform which is used in spectrum analysis and calculation of the energy density of the signal. The difference lies on the field of application.</span>
<u>Answer:</u>
The correct answer option is A. positive.
<u>Step-by-step explanation:</u>
When an exponent or a power is an even number and the base is a negative number, the value is always positive.
Suppose we have a negative base 
and a power which is even, lets say, 
so what we get is a positive value.
Therefore, a negative base with even power is always a positive value.
The first option is the correct quadratic formula
Answer:
-3/2 or 1.5
Step-by-step explanation:
5n + 10 = n + 4
5n - n = -10 + 4
4n = -6
n = -6/4
n = -3/2 (or -1.5)
