Answer:

(a) ±1/9, ±2/9, ±1/3, ±4/9, ±2/3, ±1, ±4/3, ±2, ±4

Step-by-step explanation:

The leading coefficient is 9; the constant is 4. The rational roots will be ...

±(divisor of 4)/(divisor of 9)

The divisors of 4 are 1, 2, 4. The divisors of 9 are 1, 3, 9. Then the rational roots can be any of ...

±1/9, ±2/9, ±1/3, ±4/9, ±2/3, ±1, ±4/3, ±2, ±4

Well, lets start with what you know. We know that 5 horse years is equal to 15 human years. If the horse is 16, 5 times 3.2 equals 16.
5 year old horse/ 15 year old human
16 year old horse/ ? human?
3.2 times 5 is 16. To find the answer, do 3.2 times 15, or 320% of 15. Three times fifteen is 45. 20% of 16 is 3.2. 45 plus 3.2 is 47.2! Did this help you?
