Variable a is 4 more than variable b. variable a is also 1 less than b. which of the following pairs of equations best models the relationship between a and b? 1.a = b 4 a = b − 1 2.a = 4b a = b 1 3.b = a 4 b = a − 1 4.b = 4a b = a 1

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

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
