Answer:
The zeroes in this equation are -5, -4, and 5
Step-by-step explanation:
In order to find these, you need to factor by splitting. For this, we separate out the two halves of the equation and pull out the greatest common factor of each. Let's start with the front end.
r^3 + 4r^2
r^2(r + 4)
Now the second half.
-25r - 100
-25(r + 4)
Since what is left in the parenthesis are exactly the same, we can use that parenthesis next to one with what we pulled out.
(r^2 - 25)(r + 4)
And we can further factor the first parenthesis using the difference of two squares
(r^2 - 25)(r + 4)
(r + 5)(r - 5)(r + 4)
Now that we are fully factored, set each parenthesis equal to 0 and solve for x.
r + 5 = 0
r = -5
r - 5 = 0
r = 5
r + 4 = 0
r = -4
For this case we have that by definition, the volume of a cube is given by:

Where:
l: It's the side of the cube
According to the statement data:

Substituting in the formula we have:

Thus, the shipping cube volume is
Answer:

Answer:

Step-by-step explanation:
We want to find the sum of

We can rewrite this as

This becomes;

Recall that;

This implies that;

Combine like terms:

Answer:
i think the scale factor is 3:2
Step-by-step explanation:
To figure the total difference divide:
6 divided by 4 = 1.5
1.5 = 3/2

Using scientific notation, it is found that the measure of one astronomical unit in kilometers is 
A number in <em>scientific notation</em> is given by:

- In which

- To realize the conversion from decimal to scientific notation, b is the number of decimal places the comma moves, being positive if to the left, negative if to the right.
In this problem, 1 AU = 150,000,000 km.
- The comma has to move 8 places to the right, hence

Then, the measure is:
