Answer:
-2
Step-by-step explanation:
f[g(x)
=f(3x^2+6x-2)
=2 (3x^2+6x-2)+14
=6x^2+12x-4+14
=6x^2+12x+10
f[g(-2)]=6 (-2)^2+12×(-2)+10
=12- 24+10
=-2

Answer:
90 miles
Step-by-step explanation:
Let ori. speed = z
distance = speed × time
= z × 2
= 2z miles
distance = (z - 15) × 3
= (3z - 45)miles
2z = 3z - 45
z = 45mph
distance = 45 × 2
= 90 miles
distance = (45-15) × 3
= 90 miles
