I believe the first and last one are polynomials. Usually they start with the highest exponent first and then work their way down.
Answer:
k = - 8
Step-by-step explanation:
Subtract 9 from both sides to get the constants on one side and the variables on the other
9 - 2k = 25
- 2k = 25 - 9
Simplify
- 2k = 16
Divide by -2 on both sides to isolate the variable, then simplify once more.
- 2k/ -2 = 16/ -2
k = 16/ -2
k = -8
Answer:
Step-by-step explanation:
I know that the two means are are 11.28 and 12.
I could be wrong but I did the math 5 times.
