good luck!
No, the triangular numbers are not a direct variation. There is not a constant of variation between a number and its position in the sequence. The ratios of the numbers to their positions are not equal. Also, the points (1, 1), (2, 3), (3, 6), and so on, do not lie on a line.
b6x3 + 3x + 2
c2x3 + 3x + 2
d6x3 − 3x − 2
Answer:
Option (b) is correct.
Step-by-step explanation:
Given: Polynomial and
We have to find the sum of given polynomial and choose the correct option from given options.
Consider the given Polynomial and
We have to find the sum that is
Apply plus minus rule
We have,
Now adding like terms, we have,
Like terms are terms having same variable with same degree.
Simplify , we have,
Thus, option (b) is correct.
