WILL GIVE BRAINLIEST! Find the solution sets to the following quadratic equations.
8. 5x^2 – 40 = 100

9. 9x^2 = 4x^2 + 10

10. x^2 – 4 = 80

11. x^2 + 25 = 100

12. 2x^2 + 7 = 67

13. (x^2 + 2^2)= 16

14. (x + 5^)2 = 23

15. (x – 4)^2 = 11

What is the distance between the points 4,10 and -3,-14 on the coordinate plane

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

Abcd is reflected across the x- axis, then rotated 90 clockwise about the orgin, and finally reflected across the line y= x to form a’ b’ c’ .
