Answer:
(5a - 8) + (2a² + 2a − 1) = 2a² + 7a - 9 - <u>correct.</u>
Step-by-step explanation:
(5a - 8) + (2a² + 2a − 1) = 2a² + 7a - 9 - <u>correct;</u>
(6² +6b-4) (3b +6²) = 26² +36-4 - incorrect (correct is: 18b²+...36²);
(9c-4c²) - (2c² + c) = -6c² + 10c - incorrect (correct is: -6c² + 8c).
The correlation coefficient would not change when the units of one of the variable are different in the two cases.
