Answer:
5
Step-by-step explanation:
378 divided by 9 = 42
210 divided by 42=5
The forward differences for this data is 1, 1, 1, 1, 1, 1 (since 10 - 9 = 1, 11 - 10 = 1, etc). Since we only need one iteration of differences, a linear polynomial will fit the data exactly.
Answer:
Assuming the other side is 30, x=12
Step-by-step explanation:
X+(X+6)=30
2x+6=30 (open the brackets by distributing the plus sign inside)
2x=24 (subtract 6 from both sides)
x=12 divide both sides by 12
This makes sense because of x is 6, and x+6 is 18, 6+18=30.
