The volume of the shaded region is 1650 cubic feet.
Answer:
x^2+8x+16
(x+4)^2
Step-by-step explanation:
x^2 +8x
Take the coefficient of the x term
8
Divide by 2
8/2 =4
Square it
4^2 =16
x^2+8x+16
We can factor it into
(x+8/2) ^2
(x+4)^2

Answer:
= 2 4/15 km
Step-by-step explanation:
Speed = 3 2/5 km/hour
The units are not the same. The speeds is in hours and the time is in minutes
Lets convert minutes to hours. 60 minutes = 1 hour
40 minutes * 1 hour/ 60 minutes = 40/60 hours = 2/3 hour
Distance = speed * time
= 3 2/5 * 2/3
Change the mixed number to an improper fraction
3 2/5 = (5*3+2)/5 = 17/5
= 17/5 * 2/3
= 34/ 15 km
Change this back to a mixed number
15 goes into 34 2 times (15*2 = 30) with 4 left over
= 2 4/15 km
