ade 8 Assignment State whether the following are like or unlike terms: 1.1.1. 2a and 2b 1.1.2. 2x and x2 1.1.3. 2x2 and 3x2 1.1.4. 2x2 and 2y?​

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
