The point (3/5,4) would lie on the circle if it makes the equation of the circle to be true
Latansha's equation of the circle is wrong
<h3>How to determine her error?</h3>
The given parameters are:
Center = (a,b) = (0,-2)
Radius, r = 7
The equation of a circle is:

This gives

Rewrite as:

In Latanya's first step, we have:

By comparing her first step with x^2 + (y + 2)^2 = 0, we can see that her equation is wrong
Hence, Latansha's error is that she determine the equation of the circle, wrongly.

Answer:
3 + 5x = 4x - 6
Let's do it quickly and simply,
Let's gather the like terms
5x - 4x = -6 - 3
x = - 9
Hope it helps!
Not easy:
- 4 < x^4 + 4x^2 ---> 0 < x^4+4x^2+4 = (x^2+2)^2, so it is always positive. Always satisfied. Curious ...
Now the other one:
x^4+4x^2<21 --> x^4+4x^2-21 < 0 --> (x^2+2)^2 - 25 < 0
(x^2+2)^2<25 ->>> x^2+2 < 5 ---> x^2 <3,
So -sqrt(3)<x<sqrt(3) is the answer! Brainliest?
