Use substitution to find the solution to the system of equations. 5x + 7y = -29, y + x = 1 A. (-2,-3) B. (3,4) C. (-2.5,-1.5) D. (-3,-2)

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
