The equations which are true for the values of x given are; x²-4 =0 and 4x²= 16.
<h3>Which equations are true for the values of x?</h3>
The values of x given according to the task content are; x = –2 and x = 2.
By considering equation; x²-4 =0
x² = 4
x = ±2
Also, by considering 4x²= 16;
x² = 16/4 = 4
x = ±4.

Answer: √72 or 8.49 units when rounded to the nearest hundredth.
Explanation: Because we have the endpoints if a segment and want to find the length of the entire segment, we need the distance formula.
Its general equation is √(x2-x1)+(y2-y1)
Substituting gives us √(-1-5)^2+(-9-(-3)^2
Simplifying gives us √36+36 which is √72
Also this is just a simple thing that some people forget: When you have parentheses, the exponent is distributed to everything inside including the negative. This is why we did not have a negative answer like -36 after simplifying.
