I don't think it really matters if there's a dash there or not
Answer:
Step-by-step explanation:
-5(n^3 - n^2 - 1) + n(n^2 - n)
-5n^3 + 5n^2 + 5 + n^3 - n^2
-4n^3 + 4n^2 + 5 <===
(n^2 - 1)(n + 2) - n^2(n - 3)
n^2(n + 2) - 1(n + 2) - n^3 + 3n^2
n^3 + 2n^2 - n - 2 - n^3 + 3n^2
5n^2 - n - 2 <===
n^2(n - 4) + 5n3 - 6
n^3 - 4n^2 + 5n^3 - 6
6n^3 - 4n^2 - 6 <===
2n(n^2 - 2n - 1) + 3n^2
2n^3 - 4n^2 - 2n + 3n^2
2n^3 -n^2 - 2n <===
putting them in order based on the coefficient n^2 is :
6n^3 - 4n^2 - 6
2n^3 - n^2 - 2n
-4n^3 + 4n^2 + 5
5n^2 - n - 2
Answer:
The equation is y=5x+3. If she made 48 dollars, she babysat for 9 hours.
Step-by-step explanation:
y= $48
48=5x+3
48-3=45
45=5x
45/5=9
x=9
To plot on graph, put one point at point (0,3), then, go up 5, over 1, and plot another point. Keep doing that until you have a few points and then use a ruler ot connect the dots.
I have seen this problem before, except it was worded differently. Is this the problem you wished to express?
1+4=5, 2+5=12, 3+6=21, 8+11=?
If so, then your answer is to simply add the last answer to the next problem. If not, then I am afraid I cannot help you.
1+4=5
5+2+5=12
12+3+6=21
21+8+11=40
