Given:
The side of a square is,

Required:
To find the perimeter of a given square.
Explanation:
In square, all the sides are equal.
Therefore, all sides are (s+3).
To find perimeter, we need to add all the sides,
Therefore,

Final Answer:
Option (d) is correct.
Answer:
74 feet and 6 feet
Step-by-step explanation:
Mentioned that
The Length of the dog park is = (8x + 2)............(i)
And,
The Width of the park is = (2x -12)..................(ii)
Perimeter = 160 feet
Now here we use the perimeter formula which is
Perimeter is
= 2 (length + width)
160 = 2 (8x + 2 + 2x - 12)
160 = 2 (10x - 10)
160 = 20x - 20
180 = 20x
x = 9
Now put the x value into the equation 1 and equaton 2
For the equaton 1, the length us
= 8x + 2
= 8(9) + 2
= 74 feet
And, the width is
= 2x - 12
= 2(9) - 12
= 18 - 12
= 6 feet
I'm not totally sure what you are asking, but maybe this is a question about dependent and independent variables?
If so, these types of variables are used in math and science as measures. In math, independent variables and dependent variables are the "tools" used in an experiment.
Independent variables are the variables that are controlled during the experiment. These variables do not change during the experiment.
Dependent variables are the variables whose values change based on the independent variables. These variables are the "outcome" portion.
I have no idea if this answers your question or not. All I can say is that the "controlled" part of a sample would be the independent variable.
Answer:
a. 40 / 5/2.
Step-by-step explanation:
Average speed = distance / time = 40 / 2 1/2
= 40 / 5/2.
