Solve in quadratic form

Step-by-step explanation:

The quadratic formula is a bit tedious for this since it factors so easily, but if that's what you're told to do, you should probably do it!

The quadratic formula is as follows:

For us, a = 1, b = 1, c = -2:

 which simplifies to

 which simplifies a bit more to

 which gives you the 2 solutions of

 and

0.32

step-by-step explanation:

2.24/7

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
