If Ms. Callahan has 24 feet of fencing, and she is building a pen, the PERIMETER of the pen must be 24 feet. The perimeter is basically the distance around a figure. The perimeter of a rectangle is equal to length plus width plus length plus width, AKA l+w+l+w, or P=2l+2w. In a rectangle, two pairs of sides are of equal length--so the two lengths and the two widths must be equal.
So, the formula is P=2l+2w. P, the perimeter, is 24, so 24=2l+2w. Let's try some values for l and see what we get for w. If the length is 1, l=1. 24=(2*1)+2w. 24=2+2w. 22=2w. w=11. So if length is 1 foot, width is 11 feet.
What if l=2? 24=(2*2)+2w. 24=4+2w. 2w=20. w=10. If l=2, w=10. And l=3? 24=(2*3)+2w. 24=6+2w. 18=2w. w=9. If l=3, w=9. Do you see a pattern? Every time we add 1 to l, we subtract 1 from w. So if l=4, w=8. If l=5, w=7. If l=6, w=6. Here, we start getting similar answers: if l=7, w=5. If l=8, w=4. Since we already know these values work, it doesn't matter whether we call it length or width. So, our answers are below.
Answer: Ms Callahan can make a pen with a length of 1 foot and a width of 11 feet, a length of 2 feet and a width of 10 feet, a length of 3 feet and a width of 9 feet, a length of 4 feet and a width of 8 feet, a length of 5 feet and a width of 7 feet, or a length of 6 feet and a width of 6 feet.

Answer:
Your current CD matures in a few days. You would like to find an investment with a higher rate of return than the CD. Stocks historically have a rate of return between 10% and 12%, but you do not like the risk involved. You have been looking at bond listings in the newspaper. A friend wants you to look at the following corporate bonds as a possible investment.
Step-by-step explanation:
The three numbers will be 12, 7, 2 and 3, 7, 11.
<h3>What is a sequence?</h3>
A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.
Let the three consecutive numbers be a, a + d, and a + 2d
The sum of three numbers which are consecutive terms of an A.P. is 21.
a + a + d + a + 2d = 21
3(a + d) = 21
a = 7 - d
If the second number is reduced by 1 and the third term is increased by 1 we obtain the geometric product.
Then the number will be a, a + d − 1, a + 2d + 1. Then we have

On simplifying, we have
36 = a (8 + d)
a² - 15a + 36 = 0
On factorizing, the value of a will be
a² - 15a + 36 = 0
a² - 12a - 3a + 36 = 0
(a - 12)(a - 3) = 0
a = 3, 12
If a = 12, then the value of d will be
d = 7 - 12
d = -5
If a = 3, then the value of d will be
d = 7 - 3
d = 4
Then the three numbers will be 12, 7, 2 and 3, 7, 11.
