Answer:
he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
Step-by-step explanation:
First question:
I urge you to perform the division using the synthetic division method:
________________
-4 / 1 3 -6 -6 8
-4 4 8 -8
-----------------------
1 -1 -2 2 0
Note that there is no remainder. When this is the case, the divisor (here, that's -4) is a root of the given polynomial, and the value of that polynomial, g(-4), is 0.
If the remainder were not 0, then the remainder represents the value of the polynomial for that particular divisor. For example, if x = -3, the remainder is -28. We'd write that as g(-3) = -28.
But here, g(-4) = 0.
Sn = n/2 ( a1+an)
= 6/2 (10+85)
= 3 (95)
= 285
