Answer: <em>one solution.</em>
Step-by-step explanation:
<em>This equation has one solution: x = 6.</em>
13 By the factor theorem, if the function is divisible by x - 3 then f(3) = 0. So we have:-
2(3)^3 + k(3)^2 + 7(3) - 3 = 0
9k = 3 - 21 - 54 = -72
k = -72/9 = -8 answer
14. Similarly , f(-4) = 0 , so we have:-
(-4)^3 + 9(-4)^2 + k(-4) - 12 = 0
-64 + 144 - 4k - 12 = 0
4k = -64 + 144 - 12 = 68
k = 68/4
k = 17 answer
First odd integer = x
second odd integer = x + 2
third odd integer = x + 4
sum of all three <span>consecutive odd integers:
x + x + 2 + x + 4
= 3x + 6
answer
3x + 6

Answer:
12
Step-by-step explanation:
5,5,9,12,18,22,25
First put the numbers in order from smallest to largest
There are 7 numbers
The median is the middle number
5,5,9, 12, 18,22,25
3 on the left and three on the right
12 is the median
Let's take the first derivative:
Notice that we can write this as:
By taking the derivative of both sides 
times, we get:
This means that each time you take a derivative, a factor of 
will appear. So we conclude that:
Taking 
and 
, we get:
So we finally get:
