Answer:
The first one is -2x^2 - 21x + 4, the second one is -15 (I think, not 100% sure), the third one is 4xyz + 3yz + 5x - 4 (also not 100% on this one)
Answer: False! The left side 3.75 does not equal to the right side 21, which means that the given statement is false.

Answer:
192.5 ft²
Step-by-step explanation:
Area of the sector
= (360-100)/360 x π(8.35)²
= 158.195 ft²
Area of the triangle
= 1/2 (8.35)(8.35) sin (100)
= 34.3316 ft²
Area of the shaded part
= 158.195 + 34.3316
= 192.5 ft²
