Take 8 times 4.9 and 8 times 3.7, 8 times 4.9 is 39.2 and 8 times 3.7 is 29.6 now all you have to do is subtract them numbers from each other and it gives you the answer of 9.6
Answer: 9.6
I think that the correct answer would be <span>6.5 · 10^9. but im not 100% positive

Answer: -7x3 + 13x2 + 9x - 12
Start with what we know: Our lowest number is
![p](https://tex.z-dn.net/?f=p)
and we want a sum, let's call that
![S](https://tex.z-dn.net/?f=S)
.
We know we want consecutive numbers and we want 4 of them. Numbers are consecutive if they come "one after another", that is to say: we can get from one to the other by adding or subtracting 1.
If we start with
![p](https://tex.z-dn.net/?f=p)
we can get consecutive numbers by repeatedly adding 1 (notice we aren't using the "or subtracting" part here because we know
![p](https://tex.z-dn.net/?f=p)
is our lowest number).
So: starting with
![p](https://tex.z-dn.net/?f=p)
, adding one over and over until we've got our four numbers we have:
![p](https://tex.z-dn.net/?f=p)
![p+1](https://tex.z-dn.net/?f=p%2B1)
![(p+1)+1=p+2](https://tex.z-dn.net/?f=%28p%2B1%29%2B1%3Dp%2B2)
![(p+2)+1=p+3](https://tex.z-dn.net/?f=%28p%2B2%29%2B1%3Dp%2B3)
And now we can write our sum:
