In order to remove noxious weeds from his property, a farmer sprays a weedicide over it. The chemical is slow acting and the number of weeds per
hectare remaining after t days is give by N = 20+
100
t+2
How many weeds per herb would be alive after 8 days

70,000 + 6,000 + 800 + 30

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

(23*2)-12=x     x=34
