Answer:
Step-by-step explanation:93x18= 1674
Let w be the width.
2(2w) + 2w = 54.
4w+2w = 54
6w=54.
w=9
So length equals twice that...I think you can solve that on your own. xD
Given:
The equation of circle is
To find:
The polar form of given circle.
Solution:
We have,
![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)
Subtracting 9 from both sides, we get
We know that, 
and 
.
and 
We know that, r is radius it cannot be 0. So,
Therefore, the correct option is A.
Eloise made these steps well:
Square root of negative 2x plus 1 - 3 = x
Square root of negative 2x plus 1 - 3 + 3 = x + 3
The error comes in the next step:
Square root of negative 2x plus 1 = x + 3
Square root of negative 2x plus 1 -1 = x + 3 - 1
Square root of negative 2x = x + 2
the number one is inside the root, therefore they can not be subtracted.
answer
error in the step:
Square root of negative 2x = x + 2
