Use a graphing tool and you'll see a circle form. This circle has a center of (0,0) and radius of 4. Side note: this equation is equivalent to x^2+y^2 = 16 after you divide everything by 4
Looking at the graph, the smallest x can be is -4. The largest x can be is 4. So the domain in interval notation is
![[-4,4]](https://tex.z-dn.net/?f=%5B-4%2C4%5D)
Similarly the range in interval notation is also <span>
![[-4,4]](https://tex.z-dn.net/?f=%5B-4%2C4%5D)
because the lowest you can go is y = -4. The highest you can go is y = 4</span>
It is being distributed ( ex: 5(1), bring the 5 over and multiply: 5). Since -1 is the term that is distributing for both 8m and 32, multiplying both would equal= -8m (8m x -1, + x - = negative), +32 (notice the positive, - x - = positive). In conclusion, this would be -8m+32.
<h3><u>Question:</u></h3>
A swimming pool measures 35 feet wide by 50 feet long. What is the ratio of the length to the perimeter
<h3><u>Answer:</u></h3>
The ratio of length to perimeter of pool is 5 : 17
<h3><u>Solution:</u></h3>
Given that, swimming pool measures 35 feet wide by 50 feet long
Therefore,
Length = 50 feet
Width = 35 feet
Swimming pool is usually of rectangular shape
<em><u>The perimeter of rectangle is given as:</u></em>
Perimeter = 2(length + width)
Perimeter = 2(50 + 35)
Perimeter = 2(85) = 170
Thus perimeter of pool is 170 feet
<em><u>Ratio of length to perimeter:</u></em>

Thus ratio of length to perimeter of pool is 5 : 17
Answer:
Mr. Selan would pay $2.15 for the sandwiches with tax.
Step-by-step explanation:
Given that:
Cost of each sandwich = 99 cents
Cost of two sandwiches = 99*2 = 198 cents
Sales tax = 8.5%
Sales tax = 
Sales tax = 17 cents
Total cost = 198 + 17 = 215 cents
Total cost = $2.15
Hence,
Mr. Selan would pay $2.15 for the sandwiches with tax.
2c is a factor of both terms.
.. area = 2c(c+1)
Possible expressions for length and width are
1, 2, c, 2c, c+1, 2(c+1), c(c+1), 2c(c+1).
