Step-by-step explanation:
We multiply it to find the product
positive times positive = positive
positive times negative = negative
negative times positive = negative
negative times negative = positive

Negative and negative is positive , so product is positive

Negative and positive is negative , so product is negative

positive and negative is negative , so product is negative

positive and positive is positive , so product is positive
Answer:
The boat is 5727.25ft far from the coast
Step-by-step explanation:
