Answer:
818.4 in²
Step-by-step explanation:
The area (A) of the shaded region is
A = area of circle - ( area of white sector + area of triangle )
   = ( π × 27.8²) - (π × 27.8² ×  +(0.5 × 27.8 ×27.8 × sin150°)
 +(0.5 × 27.8 ×27.8 × sin150°)
   = 2427.95 - (1416.30 + 193.21 )
   = 2427.95 - 1609.51 ≈ 818.4 in²

-2 because in the second equation it is : 2x. If you multiply x in the first equation by -2 it will cancel out 2x in the second equation. -2x cancels out 2x. -2x+2x=0
