use FOIL (first, outside, inside last)
4a * 3a = 12a²
4a * -8 = -32a
-6 * 3a = -18a
-6 * -8 = 48
-12a² - 32a - 18a + 48
combine like-terms: -12a² -50a + 48
<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>
Answer:
Do you have an attached picture?
Step-by-step explanation:
1st step. Calculate the area of the parallelogram
We can use the following formula:

where,
base, b = 9 km
height, h = 5 km
Therefore,

The area of the parallelogram is 45 km^2
2nd step. Calculate the area of the triangle
Let's use this formula:

where,
base, b = 6 km
height, h = 3 km
Therefore,

The area of the triangle is 9 km^2
3rd step. calculates the ratio of the area of the parallelogram to the area of the triangle

Answer: the area of the parallelogram is 5 times greater than the area of the triangle.
Answer:
Hypotenuse² = Base² + Altitude²
35² = 15² + x²
1225 = 225 + x²
x² = 1225 - 225
x² = 1000
<u>X = 10√10</u>
