Answer:
p=2
Step-by-step explanation:
9p-10=6+p
Subtract p from each side
9p-p-10=6+p-p
8p -10 =6
Add 10 to each side
8p -10+10 =6+10
8p =16
Divide each side by 8
8p/8 = 16/8
p =2
ANSWER
Not a factor
EXPLANATION
The given polynomial has equation:

According to the remainder theorem, if (x+5) is a remainder, then f(-5)=0.
Let us substitute x=-5 into the function and evaluate to see if it will simplify to zero.



Since the remainder is not zero, x+5 is not a factor of

Sorry i don’t know the answer.
C+p=15
5c+7p=91
multiply 5 to 1st equation and subtract it from 2nd
multiply 5 to 1st equation to get
5c+5p=75
now subtract this from 2nd equation
thats 2p=16
so
p=8
now we find c from
c+p=15
c=7
