Answer:

x is equal to 15.

Step-by-step explanation:

6/8 = x/20

Now that we have the proportion, we need to cross multiply to solve.

6*20 = 8*x

120 = 8x

Answer:

2m^2 + 14m - 81 = 0

Step-by-step explanation:

It looks like

(m + 7)/9 = 18/4m

Cross-multiplication:

4m(m+7) = 9*18
2m(m+7) = 9*9
2m^2 + 14m = 81
2m^2 + 14m - 81 = 0

Here is the quadratic equation
