Wave erosion causes a certain coastline to recede at a rate of 3 centimeters each year. this occurs uninterrupted for a period of 8 years

Solution: The expression 8(–3) represent the recession of the coastline recedes 3 centimeters each year. 8(–3)=–24 So, the coastline’s new position is 24 centimeters farther inland than it was 8 years ago

After 8 years, the coastline has receded 24 centimeters

Step-by-step explanation:

We know that each year, the coastline recedes by 3 centimeters. If this occurs uninterrupted for 8 years, then the total distance that the coastline recedes is 8 times the amount that it recedes in a year, this is:

D = 8*3cm = 24cm

After 8 years, the coastline has receded 24 centimeters
