Add 4.9 to each side so 4r>19.85 and divide both side by 4. So r> 4.96 so say any point over 5 and you are correct
D 2,4,5 it should be ( 3,4,5 )

Answer:
(x + 1)(x - 1) (x- 2)(x - 5)
Step-by-step explanation:
<u>Solving in steps:</u>
- x^4 - 7x^3 + 9x² + 7 x – 10=
- (x^4 - 1 )- (7x^3 - 7x) + (9x^2 - 9) =
- (x^2 + 1)(x^2 - 1) - 7x(x^2 - 1) + 9(x^2 - 1) =
- (x^2-1)(x^2 + 1 - 7x + 9) =
- (x + 1)(x - 1)(x^2 - 7x + 10) =
- (x + 1)(x - 1)((x^2 - 2x) - (5x - 10)) =
- (x + 1)(x - 1) (x- 2)(x - 5)
Answer:
just substitute n for 1, then 2, then 3, then 4, then 5 and write your final values equal to them.
