ddd

Step-by-step explanation:

Divide 5a2 + 6a - 9 into 25a4 + 19a2 - a - 78.

                               5a^2 -6a +20

                             -------------------------------------------------                    

   5a^2+6a-9        25a^4 + 0a^3 +19a^2 - 1a - 78

                             25a^2 + 30a^3 - 45a^2

                            ------------------------------------------------(subtract)

                                         -30a^3 +64a^2 -1a

                                         -30a^3 -36a^2 +54a

                            -----------------------------------------------(subtract)

                                                     100a^2 -55a  -78

                                                     100a^2 +120a - 180

                              ------------------------------------------------------

                                                                   - 175a +102

Quotient : 5a^2 -6a+20

Remainder : -175+102

Answer is :

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
