2:3 would be the right feet.
A interesection B means similarities between the two sets.
The possible values you can get in B are:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
A:
3, 5, 7, 9, 11
Therefore A intersection B = {3, 5, 7, 9, 11}
Answer:
5.1
Step-by-step explanation:
all you do is divide 12.55 by 2.54
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
