Let c(n) be the constant term in the expansion of (x + 4)n. prove by induction that c(n) = 4n for all n is in n. (induction on n.) the constant term of (x + 4)1 is = 4 . suppose as inductive hypothesis that the constant term of (x + 4)k − 1 is for some k > 1. then (x + 4)k = (x + 4)k − 1 · , so its constant term is · 4 = , as required.

b) the dogs need to shift their focus to human scent.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
