(a)
(b)
(c)
(d)
Answer:
Option a: is the correct answer.
Explanation:
Option a:
By substituting the values of n and expanding the summation, we have,
Subtracting, we have,
Expanding the factorial,
Simplifying, we get,
Thus, the summation represents the series
Hence, Option a is the correct answer.
Option b:
By substituting the values of n and expanding the summation, we have,
Expanding the factorial,
Simplifying, we get,
Thus, the summation does not represents the series
Hence, Option b is not the correct answer.
Option c:
By substituting the values of n and expanding the summation, we have,
Adding, we have,
Expanding the factorial,
Simplifying, we get,
Thus, the summation does not represents the series
Hence, Option c is not the correct answer.
Option d:
By substituting the values of n and expanding the summation, we have,
Expanding the factorial,
Simplifying, we get,
Thus, the summation does not represents the series
Hence, Option d is not the correct answer.
Hence, the correct answer is Option a:
Answer:
Area of a Rectangle: l x w
2 x 3 = 6
Area of a Triangle:
The slanted height of the triangle is 2 and the base of the triangle is also 2 so
So to get the area of the figure you add the area of the rectangle plus the area of the triangle.
6+2=8
The area of the figure is 8 units square
