Answer:

Step-by-step explanation:
<u>Formula:</u> 




Answer:
is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Step-by-step explanation:
Given the function

As the highest power of the x-variable is 3 with the leading coefficients of 1.
- So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.
solving to get the zeros

∵ 
as

so
Using the zero factor principle
if 


Therefore, the zeros of the function are:

is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Therefore, the last option is true.
Answer:
Step-by-step explanation: -5
1. A)
7x= 3(35)
7x= 105
105/7= 15
Therefore x=15
2. C)
Answer:
An odd number
Step-by-step explanation:
suppose n is 2.
If we add 1 into it, the answer will be 3, making it odd. same goes for any other even number if 1 is added in it
