2ab^2 + 4a - b + 3 a. Cubic, quadratic
b. Quadratic, polynomial
c. cubic, polynomial
d. quadratic, trinomial

the answer to the question is a  

it has the same slope and the same y-intercept.

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

i can't solve unless i know what the line is
