Answer:

Step-by-step explanation:
The given quadratic functions are:



We want to order these functions, from the widest to the narrowest.
How wide the graph will open depends on the absolute value of the coefficient of the function.
The smaller the absolute value of the coefficient, the wider the graph.
Since

Therefore from the widest graph to the narrowest graph, we have:

3x + 15 = 34
3x = 19
x = 6 1/3 is the answer to the question
Answer:
Perimeter of the rectangle is 16x+18 units.
Step-by-step explanation:
The area of rectangle is
First we have to find the factor form of above expression.
Splitting the middle term, we get
Area of a rectangle is the product of its dimensions. It means dimensions of the rectangle are (x+8) and (7x+1).
Perimeter of a rectangle is
Therefore, the perimeter of the rectangle is 16x+18 units.
