Explanation:

The complete question in English is attached.

The equation is:

The commutative property of the multiplication states that the order of the factors do not change the product.

Thus, the product a · b is equal to the product b · a.

In the given equation the order of the factors 2/5 and 5/2 was changed: in the left-hand side it appears 2/5 · (5/2). On the right-hand side it appears as 5/2 · (2/5).

Thus, the equality shows the commutative property of the multiplication of rational numbers.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
