I need help with this question! I would really appreciate it if you would show the steps.

Yuck! That one looks nasty... it's actually not too bad. Let's take it in steps.

[1] Understand the question. We need to find the greatest common factor (GCF). The GCF is exactly what it says, it is the biggest factor in common to all the numbers being added or subtracted.

Once we find the GCF, it is easy to factor the expression (which is why they are forcing you to find it!).

[2] Let's start with the obvious numbers, 8, 2, and 10. What's the GCF of those?

Well... that has to be 2. I can factor anything bigger out because 2 itself would be gone!

[3] Let's move on to the variables... v^6, v^5, v^9. What's the GCF of those?

Well... I the most I can factor out is v^5.

[4] Putting it all together the GCF of this expression is 2v^5. Great!

[5] Now, we factor this out of the expression:
2v^5 (4v + 1 - 5v^4)

Check by multiplying it back:
2v^5 * 4v + 2v^5 * 1 - 2v^5 * 5v^4 = 8v^6 + 2v^5 - 10v^9
and we get back what we wanted.

The answer is 2v^5 (4v + 1 - 5v^4).

The sum of 3 consecutive integers is 78. What is the integer closest to zero?
vova2212 [387]

Answer:

25

Step-by-step explanation:

Let n be the first integer.

Then the second integer will be (n + 1).

And the third will be (n + 2).

The sum is 78. Therefore:

n+(n+1)+(n+2)+78

Solve for n. Combine like terms:

3n+3=78

So:

3n=75

Therefore:

n=25

Therefore, the first integer is 25.

So our sequene is 25, 26, and 27.

The integer closest to zero will thus be 25.

Determine the term life insurance amount per thousand on a 22-year-old female for a 5-year policy given that the face value of t
VLD [36.1K]

We need to determine the term life insurance amount per thousand on a 22-year-old female for a 5-year policy given that the face value of the policy is $600,000 and the annual premium is $1332.

Since we are supposed to find the term life insurance amount per thousand, therefore, we will use the following formula:

\text{Term life insurance amount}=\frac{\text{Annual premium}}{\text{Face value of insurance}}*1000

Upon substituting the values of annual premium and face value of insurance, we get:

\text{Term life insurance amount}=\frac{\text{1332}}{\text{600000}}*1000\\
\text{Term life insurance amount}=\$2.22

Therefore, the required life insurance amount is $2.22.
