= 2n^4 - 8 - 3n - 4n^2 - 7n - 4
Now simplify like terms
= 2n^4 - 4n^2 - 10n - 12
= 2(n^4 - 2n^2 - 5n - 6)

I know that bc I had the same question on khan academy
Just do this 550+450=1000-120=880=750=1630 Now I assume that what you meant to say was what percent of the new balance was the last deposit made. So thats what Im going to be answering off of. We would need to take 1630-750=880 then 880/1630=.54 (rounded to the nearest hundredth) then we need to subtract 54 from one hundread because .54 is how much that the account overgoes the latest deposit making are final answer. That the last deposit that she mad accounted for 46% of the entire account. Enjoy!=)
