What is the result of factoring out the greatest common factor from the polynomial 15u3 + 9u2v - 18uv2?
a
3uv (5u^2 + 3u - 6v)
b
3u (5u^2 + 3uv - 6v^2)
c
uv (15u^2 + 9u -18v)
d
u (15u^2 + 9uv - 18v^2
Answer:
B
Step-by-step explanation:
By looking at the problem, we can realize that all the three terms share the constant 3 and the variable u, so 3u is our GCF. Now, we factor out 3u, and divide each term by 3u to show what's left:
3u( 15u^3 / 3u + 9u^2v / 3u - 18uv^2 / 3u)
15u^3 / 3u --> 5u^2
9u^2v / 3u --> 3uv
- 18uv^2 / 3u --> -6v^2
3u(5u^2 + 3uv - 6v^2)
This aligns with option B, so B is the answer.
hello this is two step equations.
2 = c/4 -1

The school store sells bottles of water and soft pretzels during lunch. Each bottle of water costs $0.75, and each pretzel costs $1.25. During one lunch period, the number of water bottles sold and the number of pretzels sold added up to 97, and the store made $96.25. Which system of equations could you write to answer this question: How many bottles of water, w, and how many pretzels, p, did the school store sell?
a.) w + p = 97
1.25w + 0.75p = 96.25
b.) w + p = 96.25
1.25w + 0.75p = 97
c.) w + p = 97
1.25w + 0.75p = 96.25
d.) w + p = 97
0.75w + 1.25p = 96.25
Answer:
D
Step-by-step explanation:
The first equation will have to do with the the quantities sold.
We know that 97 total items were sold so
w + p = 97
The second equation has to do with prices.
Our final profit was 96.25 so we tag on each individual price to the different items sold. This amounts to the final profit.
0.75w + 1.25p = 96.25
----------------------------------------------------
w + p = 97
0.75w + 1.25p = 96.25
Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.
His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.
In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.
Assuming there are no outliers or skew, do the results support Garret's theory?
Select from the drop-down menus to correctly complete the statements.
Since the samples were large and randomly chosen, we can use the samples to understand the populations.
Because the sample mean for students with a grade point average of 3.0–4.0 is
