5. A biologist recorded the population growth of two species of frogs in a pond area starting in 2010. The first species started with 42 frogs and
increased by 6 frogs per year. The second species started with 30 frogs and
increased by 8 frogs per year.
A. Write an equation modeling equal populations of the frogs t years
after 2010.

452,489 to the nearest thousand is 452,000

step-by-step explanation:

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
