Given the polynomial function

If (x-3) is a factor of P(x), then

, for some polynomial Q of 1st degree,
Then according to the factor theorem P(3)=0, because P(3)=(3-3)Q(x)=0*Q(3)=0.
Check

≠0
we see that P(3) is not 0, so (x-3) is not a factor of P(x).
Answer: no
I'll answer and explain, its pretty much the last question. Easy way to put it,
1 and 4 are diagonal from each other so they are the same number.
1 and 4 = 120
2 and 3 are diagonal so they both = 60
Same thing for the bottom
1=120
2=60
3=60
4=120
5=120
6=60
7=60
8=120
Answer:
72 degrees
Step-by-step explanation:
Because you want subtract both of the number from 180 because triangles angles always have to equal 180 degrees. I hope that helped! :)
