Answer:
We should attempt synthetic division to find when
x
3
−
k
x
2
+
2
k
x
−
15
x
−
3
has a remainder of
0
, which would signify that it is a factor of the polynomial.
The synthetic substitution would be set up as:
3
−
∣
∣
∣
1
−
k
2
k
−
15
−−−
−−−
−−−
−−−
−−−
|
0
Treating the synthetic division like any other synthetic division problem, we see that
3

If the remainder equals
0
, then we know that
−
3
k

(
−
15
)
=
0
Solve this to see that
k
=
4
.
Thus,
(
x
−

)
is a factor of
x
3
−

x

Answer:
The average number of pounds they bought was 30 pounds.
Step-by-step explanation:
we know that
To find out the average number of pounds, add the total number of pounds for each boy and then divide by the number of boys.
so
therefore
The average number of pounds they bought was 30 pounds.
It would be c or d because the pic shows you how it is slanted
Answer:803.84
Step-by-step explanation:
3.14 x (16^2) = 803.84.
16^2 is 256 so multiply that by 3.14
If itt says 4×3+6 it is 18 and it means you can either multiply first
