Answer:
8x^2-x-8
Step-by-step explanation:
6x^2 + 3x – 9-(- 2x^2 + 4x – 1 )
6x^2 + 3x – 9+2x^2 - 4x + 1
6x^2+2x^2+ 3x- 4x -9+1
8x^2-x-8

See the attached picture to better understand the problem
we know that
in the right triangle ABC
tan 9.2°=BC/AC-----> BC=AC*tan 9.2°----> BC=22*tan 9.2°---> BC=3.56 ft
<span>the height of the basketball hoop=BC+CD----> 3.56+5.6----> 9.16 ft
</span><span>the height of the basketball hoop=9.2 ft
the answer is</span><span>
the height of the basketball hoop is 9.2 ft</span>
