F(x) = 4x – 6. Which steps are a correct way to find f(2)?

Step-by-step explanation:

f(x) means the same thing (just about) as y. Think of it as the y value.

f(2) means that wherever you see an x on the right, you make it into a 1.

So f(2) means 4(2) - 6 = 8 - 6 = 2

A us the correct answer. Everything else cannot be made to produce 2 or at least not the right way

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
