2.\\-3f^2+4f-3+8f^2+7f+1\\=5f^2+11f-2\leftarrow C.


3.\\(2x^2+6x+1)+(-7x^2+2x-3)\\=2x^2+6x+1-7x^2+2x-3\\=-5x^2+8x-2\leftarrow B.

Please can u help me with geometry work !!!

The first one can be done by Pythagoras theorem such as 12^2=9^2+x^2 then x^2=63 then x= \sqrt{63}

The second one can also done by Pythagoras theorem, note that this is isosceles triangle so y=z, again by using Pythagoras theorem 15^2=y^2+z^2=y^2+y^2 or =z^2+z^2 then 225=2y^2 then y= \sqrt{\frac{225}{2} }

For the last one  can also done by property of 30-60-90 triangle. w=8 \sqrt{3}k=2.8=16
