Answer:
4n - 2
Step-by-step explanation:
Greater = 2n
Smaller = 2n - 2
Sum = 2n + (2n - 2)
Sum = 2n + 2n - 2
Sum = 4n - 2
Answer:
area of shaded part = 52 pi m^2
Explanation:
1- getting the area of the largest circle:
area of circle = pi * (8)^2 = 64 pi m^2
2- getting the area of the while circle including the small shaded circle:
area of circle = pi * (4)^2 = 16 pi m^2
3- getting the area of the small shaded circle:
area = pi * (2)^2 = 4 pi cm^2
4- getting the area of the shaded part:
area of shaded part = part 1 - part 2 + part 3
area of shaded part = 64 pi - 16 pi + 4 pi
area of shaded part = 52 pi m^2
Hope this helps :)
When multiplying or dividing with negative and positive numbers, if the signs are the same, the result is positive...when the signs are different, the result is negative.
so a positive divided by a negative results in a negative...because the signs are different.
but if it was a negative divided by a negative or a positive divided by a positive the result would be positive because the signs are the same.
