What are 3 possible equivalent expression that you could write for the expression below? one of your possible ways must include parentheses there are 4 x terms and 6 m terms
x+x+x+x+m+m+m+m+m+m

what's the question?

step-by-step explanation:

there is no question.

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
