Answer:
(fg)(x) = 6x³ - 2x² + 12x - 4
Step-by-step explanation:
( f g ) ( x ) = f ( x ) * g ( x )
f(x) = 2x² + 4
g(x) = 3x – 1
( f g ) ( x ) = (2x² + 4) (3x – 1)
= 6x³ - 2x² + 12x - 4
Answer:
x = 17
Step-by-step explanation:
x + x + 8 = 42 because x = boys and x + 8 = girls
2x = 34 because 2x = 42 - 8
x = 17
i hope this helps! you don't need the 2x = 42 - 8 to be an equation ;)

s=18x6
s=108
Answer:
3) 180°-50°=130°
4)90°-50°=40°
Step-by-step explanation:
5)angle DEC=50°(VERTICAL OPPOSITE ANGLE)
x=50°-15°=35°
6)Y+30°+50°=180°(linear pair)
Y=180°-80°
Y=100°
