I'm not sure if this is correct but (x + 9) • (x - 9)
If you would like to solve 9 <= 17 - 4x for x, you can do this using the following steps:
9 <= 17 - 4x
4x <= 17 - 9
4x <= 8 /4
x <= 8/4
x <= 2
The correct result would be x <= 2.
256 ft squared would be around 65,000 ft.
210 miles in 3 hours = 210/3 = 70 mph
so time t travel 350 miles will be 350/70 = 5 hours
Answer:
Option B
80 in²
Step-by-step explanation:
Volume, V of any shape is the product of cross-sectional area and height. Therefore, V=Ah
Where A is the cross sectional area and h is the height.
Making A the subject of the formula then
A=V/h or V÷h
Substituting 400 in³ for V and 5 in for h then
A=400 in³÷5 in=80 in²
Therefore, the area of base is 80 in²
