Answer:
Right side towards positive x axis
Step-by-step explanation:
Let us see the basic rule to find the orientation of parabolas.
1. If power if x is 2 and y is 1 , the parabola opens up or down.
2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.
3. If the coefficient of
in case 1 is negative it opens downward
4. If the coefficient of
in case 2 is negative , it opens left towards negative x axis.
Hence our equation is

here is satisfies the case 2. hence it opens right or left . Also the coefficient of
is positive so it opens up to the right side , that is towards positive x axis.
Answer:
area(rectangle) = Length * width
8w + 18 = 2 * w
8w + 18 = 2w
x + x +2 + x + 4 = 120 ( I think you mean linear equation!)
3x = 114
x = 38
the numbers are 38, 40 and 42
