Answer:
x^2 + 10x - 24 = 0
Step-by-step explanation:
Two zeros are 2 and -12:
- x - 2 = 0
- x + 12 = 0
So the function is (x-2)(x+12) = 0
<=> x^2 + 12x - 2x - 24 = 0
<=> x^2 + 10x - 24 = 0
If we let x be the speed of the boat you are taking to the island (the steamboat), then we know that the speed of the other boat (the tall ship) is 10 knots less than the steamboat's. So the speed of the tall ship (for the return trip) is (x - 10) knots.

Answer:
37.5% probability of the spinner landing on the number that's greater than five
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
There are 8 total sections, from 1 to 8.
3 of those sections, 6, 7 and 8, are numbers that are greater than five.
3/8 = 0.375
37.5% probability of the spinner landing on the number that's greater than five
