y-1700=200(x+4)
step-by-step explanation:
200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
56.6
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
