The width of a rectangle is 5 units less than the length. the area of the rectangle is 6 units. what is the width, in units, of the rectangle?

The width of rectangle is 1 unit.

Step-by-step explanation:

Given:

The area of rectangle is 6 units and its width is 5 units less than the length.

So, to find the width of rectangle.

Let the length be and the width be .

Now, to find the width we put the formula of area of rectangle:

Area = length × width

On solving equation we get:

Therefore, we take the value x=6 as it is positive value:

So, the width of rectangle:

Width =

          =

          =

Therefore, the width of rectangle is 1 unit.

Part A: The given scatter plot represent the positive relation between temperature and sales of popsicles.

Part B:The equation of best fit line is . Slope of the line is 1/5 and y-intercept is 2.

Step-by-step explanation:

Part A:

From the given graph it is clear that x-axis represents the temperature in Fahrenheit and y-axis represents the number of popsicles she sold daily.

From the given scatter plot it is clear that the number of popsicles she sold daily increases as the temperature increases.

Therefore the given scatter plot represent the positive relation between temperature and sales of popsicles.

Part B:

The given scatter plot represent the positive relation between two variables and it represents strong positive correlation because the data points lie about a straight line.

Let the two points on the best fir line are (40,10) and (90,20).

The equation of best fit line is

Add 10 on both the sides.

Therefore, the equation of best fit line is . Slope of the line is 1/5 and y-intercept is 2.
