C. 30 ;because although it is divisible by 5, it is not an odd number. 30 is still an even number. Thus, 30 counters the statement.
We can start with the first two sets
(x+3i)(x-3i) = x²-9i² then simplify it to x²+9
multiply the next two
(x+1)(x-1) = x²-1
then multiply those two together
(x²+9)(x²-1) = x∧4-x²+9x²-9
combine like terms x∧4+8²-9
that is your answer

Answer:
3985
Step-by-step explanation:
Note: predecessor means a number before for example predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.
The predecessor of the predecessor of 2987 = 2987-2 = 2985
Let 2985 be x
The greatest 3 digit number = 999
And the successor of the greatest 3 digits number would be = 999+1 = 1000
let 1000 be y
We have find the sum of x and y
= 2985+1000
= 3985
