Answer:
y=3(x-9)^2+4
Step-by-step explanation:
To move a parabola horizontally to the right, subtract 9.
To move it upward 4 units, you simply have to add 4.
These do not change the characteristics of the shape. I suggest looking at a set of rules that affect how the parabola moves horizontally and vertically.
Step 1: 13+5x=30
step 2: subtract 13 from both sides; then youd get 5x=17
step 3: divide by 5
step 4: x=3.4

Let the width be X
Then the length is X + 70
The perimeter is the sum of all sides
There are 2 widths (left side and right side) and 2 lengths (top and bottom)
Perimeter = 2 * width + 2 * length
Perimeter = 2 * X + 2 * (X+70)
Perimeter: 2 X + 2 X + 140 = 380
4 X = 380-140
4 X = 240
X = 240 / 4
X = 60
Width = 60 - the smaller of two sides
Length = X + 70 = 60 + 70 = 130 - the larger of two sides

2 * 60 + 2 * 130 = 380 </span>
