Answer:
n+(n+2)+20=4n
Step-by-step explanation:
Let the smaller integer be n,
the bigger odd integer will be n+2.
n+(n+2)+20=4n
2n+22=4n
2n=22
n=11
Answer:
Part 1) The area of the figure is
Part 2) The perimeter of the figure is 
Step-by-step explanation:
Part 1) Find the area of the figure
we know that
The area of the figure is equal to the area of three squares
so
![A=3[4^2]=48\ cm^2](https://tex.z-dn.net/?f=A%3D3%5B4%5E2%5D%3D48%5C%20cm%5E2)
Part 2) Find the perimeter of the figure
we know that
The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)
Remember that
The circumference of a circle is equal to

where
D is the diameter of the circle
In this problem

so
![P=2(4)+3[\pi(4)]=(8+12\pi)\ cm](https://tex.z-dn.net/?f=P%3D2%284%29%2B3%5B%5Cpi%284%29%5D%3D%288%2B12%5Cpi%29%5C%20cm)
simplify

The answer is 24,000. the thousands place is 0,000. place 2 in ten thousands 20,000 place 4 in thousands 24,000 and... there's nothing else to do. the answer is 24,000.
Answer:
A) Yes, 7
Step-by-step explanation:
The given sequence An = {13, 20, 27, 34, ...}
Here the first term Ao = 13 and difference between the successive terms is (d) = 7
That is d = 20 - 13
d = 7
It is an arithmetic sequence. d = 7
Answer: Yes, it is arithmetic sequence and common difference (d) = 7
Thank you.
