5x-2x+6x+40-9+1-x+3x-8+15+7
First you would combine like terms:
5x - 2x + 6x - x + 3x = 11x and
40 - 9 + 1 - 8 + 15 + 7 = 46, so the simplified expression would be
11x + 46
V = 1/3 l h w
V = 1/3 (12)(15)(9)
V= = 540
answer 540 m^3
Answer:
This sum is the sum of an arithmetic sequence. There is a formula for the sum of an arithmetic sequence which can be looked up or derived by a variety of means.
A nice approach for this sequence is the following. Notice that the sum of first and last number in the sequence is the same as the sum of the second and second last, and also the same as the sum of the third and third last, and so on.
There are n of these pairs. So the desired sum is n x (first number + last number). But the first number is 1 and the last on is 2n. Thus the desired sum is n(1 + 2n).
Hope this helps!!

The last option because it’s the one that makes that will get you the sum need when added with the other polynomial
Answer:
350 will be your answer :)
Step-by-step explanation:
so i did 70 divided by 2 because 140 divided by 70 = 2
and 70 divded by 2 IS 35!
But wait that isn't what it's asking for right?
then i did 35 TIMES 10 cuz that's what it;s asking for
i got 350 and so should you so in conclusion 350 is your answer
Hopefully this helped!
