A popular beach erodes 4 inches per year on average. The number line below shows the expected change in the coastline as years pass. How could you use the number line to show the erosion after 10 years?

U would mutiply 4inchesx10 years and get 40inches then u would plot it onto the line 40 back to show

Step-by-step explanation:

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
