The demographer predicts that the population P of the town t years from now can be modeled by the function P(t)=6t^4-5t^3+200t+12000.P(t)=6t^4 −5t^3 +200t+12000. In how many years will the population of the town be 936,000?

452,489 to the nearest thousand is 452,000

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

true
