Which of the following shows figure T rotated 90° clockwise around the Orgin ?

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

It's the 4th one because it's the only one that rotated at 90° clockwise and around the origin.

Take the coefficient of the x-term, half it, then square that. add this to both sides

x² + 16x. coefficient of x is 16. half of 16 is 8. 8²=64

x² + 16x + 64 =64. this is your answer but to continue

x² + 16x + 64 = 64
(x+8)² = 64
x+8 = ✓64
x+ 8 = ±8
x = 0 or -16
