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.

The domain of the exponential function is all real numbers.
3x-4= 6x-19 » -4+19 = 6x-3x » 15 = 3x » 15/3 = x » x = 5
Answer:
(x + 15) / 2
Step-by-step explanation:
Distance = rate × time
d = (x² – 225) / (2x − 30)
d = (x – 15) (x + 15) / (2 (x – 15))
d = (x + 15) / 2
