The equation would be (x^2)/2 = 18

(x^2)/2 = 18

x^2 = 36

Because there is no square root, x can be positive and negative.
The answer would be 6 and -6.

Almons:walnuts:rasins=1:2:3

x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute

12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins

1/3 pound walnuts
2/3 pound almonds
1 pound rasins

Use the same formular

$\boxed { m= { \frac{y_1 - y_2}{x_1 - x_2} } } \\ m= { \frac{0 - 1.5}{-3 - 0} } \\ m= { \frac{-1.5}{-3} } \\ m= { \frac{1}{2} }$
