10√2 is the answer for square root of 200
Answer:
The remaining area in the form of a polynomial function
where 0 < x < 3.
Step-by-step explanation:
Breadth of rectangular piece of cardboard = 7 inches
Length of rectangular piece of cardboard = 20 inches
Area of cardboard = 
Area of cardboard = 
Area of cardboard =
Squares of length x inches on a side cut from each corner.
Length of square = x
Area of 1 square = 
Area of 4 squares = 
Area of remaining portion 
So, the remaining area in the form of a polynomial function
where 0 < x < 3.
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x -----> the number of pumpkins (independent variable or input value)
y ----> the cost of the pumpkins (dependent variable or output value)
we have that
For x=4, y=11
Find the value of the constant of proportionality k

The linear equation is
