Answer:
Assuming "x2" is x squared:
5x(x2-4x+2)
(5x(x2)+5x(-4x)+5x(2))
<u>5x^3-20x+10x</u>
For these polynomial multiplication problems, just distribute the number outside the parentheses.
Data: (Cylinder)
h (height) = 8 cm
r (radius) = 5 cm
Adopting:

V (volume) = ?
Solving:(<span>Cylinder volume)
</span>




<span>Note: Now, let's find the volume of a hemisphere.
</span>
Data: (hemisphere volume)
V (volume) = ?
r (radius) = 5 cm
Adopting:

If: We know that the volume of a sphere is

, but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (<span>Volume of the hemisphere)
</span>

Solving:





<span>Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)
</span>
Volume of the figure = cylinder volume + hemisphere volume
Volume of the figure = 628 cm³ + 261.6 cm³
Answer: The actual distance is 68 miles.
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
4² -3×8÷2/3+5
then multiply -3×8= -24
then 4²-24÷2
then divide -24÷2 = -12
then subtract 16-12=4
then that leaves 4/8= 1/2
Answer:
m > 6
Step-by-step explanation:
-2/3m<-4
-2/3 * m < -4
m > -4 * (-3/2)
m > -2 * -3
m > 6
