I’m not sure but I think graphing it would help I really don’t know what to say
Let's define variables:
x1: gear 1
x2: gear 2
The relationship between gears is:
x1 / x2 = (1 1/2) / (1/2)
Rewriting:
x1 / x2 = (3/2) / (1/2)
x1 / x2 = (3 * (1/2)) / (1/2)
x1 / x2 = 3
Another unit rate is:
x2 / x1 = (1/2) / (1 1/2)
x2 / x1 = (1/2) / (3/2)
x2 / x1 = (1/2) / (3 * (1/2))
x2 / x1 = 1/3
Answer:
two unit rates to represent the gear ratio are:
x1 / x2 = 3
x2 / x1 = 1/3

Answer:
The values of x is 0 and 2.
Step-by-step explanation:
Given that the perimeter and area are the same so we can assume that x value remains the same in both equation. In order to find x, we can compare the equations and solve it :
A(y) = x² - 4x + 4
P(y) = -2x + 4
A(y) = P(y)
x² - 4x + 4 = -2x + 4
x² - 4x + 4 + 2x - 4 = 0
x² - 2x = 0
x(x - 2) = 0
x = 0
x - 2 = 0
x = 2
