Let's complete the square. We get:
(x^2-30x)+y^2+221=0
(x^2-30x+225)+y^2+221-225=0
(x-15)^2+y^2-4=0
(x-15)^2+y^2=4
By analyzing this, we see that the radius is just :[tex]\sqrt{4}[/tex]=2
What is the area of a square with side lengths of 3/5 units? Please explain how you know.

Ribbon costs $1.25 per meter. What would be the cost of 250 centimeters rounded to the nearest cent? HINT:
centimeters to meters before calculating the price
Answer:
The answer should be $3.125 or $3.13 rounded.
Step-by-step explanation:
First I divided 1.25 by 100 because 1 meter equals 100 centimeters.
1.25 ÷ 100 = 0.0125
Now that we know that it costs 0.0125 for 1 centimeter we multiply it by 250.
0.0125 * 250 = 3.125
Since it says to round to the nearest cent, the answer should be 3.13
Hope this helps! :)

Part A: find the value for x:
Part B: what is the value of angle A?
Answer:
part A:
If ABC is a triangle then,
2x+4+2x-9+x=180degree
or, 5x-5=180degree
or, 5x=(180+5)degree
or, 5x= 185degree
or, x=185÷5 = 37degree ans.
PartB
now put the value of x in angle A
i.e angle A = 2x-9
or, angle A= (2×37) - 9
or, angle A= 74 - 9
therefore, angle A= 65degree ans.

write the following decimals in the form of p\ q= 0 and p,q are con-primes 1) 15.265
Given:
The decimal number is 15.265.
To find:
The decimals in the form of [tex]\dfrac{p}{q}[/tex] and p,q are co-primes.
Solution:
Let the decimal number be [tex]x=15.265[/tex].
It can be rewritten as
[tex]x=15.265\times \dfrac{1000}{1000}[/tex]
[tex]x=\dfrac{15265}{1000}[/tex]
[tex]x=\dfrac{5\times 3053}{5\times 200}[/tex]
Cancel out the common factors.
[tex]x=\dfrac{3053}{200}[/tex]
Here, p=3053 and q=200 and the HCF of (p,q) is 1. So, p and q are co-primes.
Therefore, the requited fraction form is [tex]\dfrac{3053}{200}[/tex].
can anybody help pls
Answer:
2t
Step-by-step explanation:
The expressions are not the same because different terms are negative. We can visualize the difference by rewriting the expressions as 13t + (-2t) and (-13t) + 2t. In the first expression, 13t-2t, the 2t is negative because it is being subtracted, and subtracting a number is the same as adding a negative.
