Answer:
Step-by-step explanation:
9, because 18 multiplied by 3 is equal to 54
54 multiplied by 2 is equal to 108
And,
108 divided by 12 is 9.
3(x^2+10x+5)-5(x-k)=
3x^2+30x+15-5x+5k=
3x^2+25x+15+5k
for this to be divisible by x every term must include x or get eliminated
the problematic terms are 15 and 5k
to eliminate them they must equal 0 when added:
15+5k=0
5k=-15
k=-3
so A) -3 is the solution
Answer:
undefined
Step-by-step explanation:

The above equation is applicable for each and every value of a,
So, Correct option is A. True
