What is the square root of 504 simplified ?
1 answer:
Answer:
6
Step-by-step Explanation:
To simplify , we will look for numbers that 504 can be divided by until there are no perfect square roots under the radical.
[] To do this, we can think of perfect square roots such as 4, 9, 16, etc
We can divide 504 by 36 for an answer of 14, so can be written as
which can be written as 6
because the square root of 36 is 6.

Answer: r=√6 or r≈2.45.
Step-by-step explanation:
To find the radius, you first need to know the equation of a circle.
Equation of a circle:
Now that we know the equation of the circle, we can use it to find the radius of the given equation.
3.5(x+2.2)²+3.5(y-11.1)²-21=0
So far the equation looks pretty similar with the exception of the bolded areas. To get rid of them, we need to use our algebraic properties.
3.5(x+2.2)²+3.5(y-11.1)²-21=0 [add both sides by 21]
3.5(x+2.2)²+3.5(y-11.1)²=21 [factor out 3.5]
3.5((x+2.2)²+(y-11.1)²)=21 [divide both sides by 3.5]
(x+2.2)²+(y-11.1)²=6
Now, our equation is the same as the one posted above. You may think that 6 is our radius, but if you look closely, the equation is equal to r². Therefore, 6 is actually r², not r.
r²=6 [square root both sides]
r=√6
Finally, we have the final answer, r=√6 or r≈2.45.
Heyoo. I included it as a photo but if you can’t see it… in expanded form the answer is B, in simplified form the answer is D and it in factored form the answer is A. I hope this help! If you need me to explain anything feel free to ask.
