A.
Step-by-step explanation:
A fence is needed for the circular field.
Circumference is basically perimeter but for circles.
Knowing this information, we can use the formula for circumference.
C = d
C = (3.14)(50)
C = 157

Answer:
See attached
Step-by-step explanation:
Solution is in the attached picture
Given:
The equation is:
To find:
The slope intercept form of the given equation.
Solution:
Slope intercept form of a line is:
Where, m is slope and b is y-intercept.
We have,
It is not in the slope intercept form.
We need to isolate variable y to get the slope intercept form.
The given equation can be rewritten as:
Therefore, the slope intercept form of the given equation is .
This problem requires multiple steps, so please read through the whole answer to get a good understanding on how to solve this problem
Step 1: Create an equation for the perimeter respect to x
The equation for the perimeter p is:
where w is the width and l is the length
The length is 3x+4 and the width is 2x-1, so substitute these values into the equation:
This is the equation for the perimeter
Step 2: Solve for x since we are given the perimeter
We are given that the perimeter is 96, thus we can create the equation:
Subtract 6 from both sides
Divide both sides by 10
We have now found the value of x
Step 3: Find the length and width now that we know x
Plug the value of x into the expressions for the length and the width that we are given
Step 4: Solve for the area now that we know the dimensions
This is probably the easiest step. Multiply the length and width to find the area:
The area of the patio is 527.
I've double- and triple-checked that this is the correct answer, so do not worry about any errors.
