Can you help me solve these math problems? Specifically, I need help with trigonometry, matrix multiplication, and solving quadratic equations.

It looks like we've already covered all the questions from this image in our previous interactions. We've solved:

• The trigonometry problem (finding $\sin PRT$, $\cos QPR$, $\cos PRT$, and $\tan QPR$).
• The matrix multiplication problem to find $x$.
• The equation $(3x-1)^2 = 12$.
• The equation $(2x-1)^2 = 25$.

If you have a new question or would like to review any of the previous solutions, just let me know! Send me the next one 📸
