Answer:B
Step-by-step explanation:
Not sure but the math came out like that.
Answer:
-2
Step-by-step explanation:
The leading coefficient in a polynomial is the coefficient that corresponds with the highest degree term. In this case, -2 is the leading coefficient since its term has x² as the highest degree of the quadratic.
Answer:
Lateral surface area is the round part/the middle part of the cylinder, not the bases

Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° = 
= 
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )
